Use this trick to Save time : HDL Simulation through defining clock

Why is this trick useful? Defining a clock in your simulation can save you time during simulation because you don't have to manually generate the clock signal in your simulation environment. Wanted to know how to define and force clock to simulate your digital system. Normally define clock used to simulate system with clock input. But I am telling you this trick for giving values to input ports other than clock. It will help you to save time in simulation because you do not need to force values to input ports every time. Lets brief What we did - gave some clock frequency to input A, like we gave 100. Than we made Half the frequency of clock to 50 and gave it to Input B. In similar way if we have 3rd input too we goanna half the frequency again to 25 and would give to next input.

On Multitasking

Sharing a Computer with Friends

The Motorola 68030 was a decently powerful microprocessor for its day. It is a fully 32-bit processor with 16 general-purpose registers, separate instruction & data caches, memory management unit, 18 addressing modes, over 100 instructions, pipelined architecture, and was available rated up to 50MHz. It was used in computers by Apple, Amiga, NeXT, Sun, Atari, and saw further life embedded in devices such as printers, oscilloscopes, and network switches. It was the kind of microprocessor used for desktop publishing, 3D CAD & animation, photo & video editing, etc.

In short, the 68030 is a microprocessor that can do some serious work. That's part of why I like it so much. It's a real workhorse chip but as far as 32-bit microprocessors go, it's dead simple to build with.

But running a single quick & simple BASIC program hardly seems like an adequate exercise for such a capable chip.

There is a prevailing claim that the 68000 architecture was heavily inspired by that of the PDP-11 or VAX minicomputers — powerhouses of the previous generation of computing. These machines ran entire businesses, at times servicing many simultaneous users. Surely the 68030 with similar capabilities but significantly faster instruction throughput than the decade-older machines would be more than capable of handling such a workload.

As I've mentioned before, one of my end goals for my 68030 projects is to run a proper operating system. Something like System V, BSD, or Linux; a true multi-user system befitting of the 68k's architectural heritage. My programming skills are limited, and getting such a complex project running is still outside my reach. But I am learning, and slowly inching myself closer to that goal.

Recently I built an expansion card for my Wrap030 project to add another four serial ports to it. In the context of the old minicomputers, another serial port means another terminal, which means the ability to serve one more user. My new 4-port serial card should give me the ability to add four new user terminals.

If only I had software capable of doing so.

Excluding symmetric multiprocessing and today's multi-core behemoths, supporting multiple user processes on a single computer processor means dividing time between them. The computer will run one user's program for a little while, then stop and run another user's program for a little while. Do this fast enough and neither user might ever notice that the computer is paying attention to someone else — especially since the computer spends much of its time just waiting for user input.

There are a few ways to accomplish this, but the simplest is to just make sure that every user program is written to cooperate with the others and periodically yield to the next user program ("Cooperative Multitasking"). A good time to do this is whenever the program needs to wait for input from the user or wait for a device to be ready to accept output.

Enhanced BASIC (68k EhBASIC), which I have been running on all of my 68k computer builds, was written in such a way that lends itself well to this sort of cooperative multitasking. It runs a tight loop when waiting for input or output, and while running a BASIC program, it stops at the end of each line to see if the user has pressed Ctrl-C to stop the program. This means that EhBASIC never goes too long without needing to check in with slow I/O devices. All that would needed is a simple kernel to set things up and switch to another user's processes whenever each time one of them is waiting for I/O.

So I set about creating such a minimal multi-user kernel. On startup, it initializes hardware, sets up some data tables for keeping track of what each user program is doing, loads BASIC into RAM, then starts running BASIC for that first user. Whenever a user process needs to read data from or write data to its terminal, it asks the kernel to handle that I/O task for it. The kernel will save the state of the user program to the data table it set up in the beginning, then switch to the next user to let it run until it too asks for assistance with an I/O task.

The kernel works through all user processes round-robin until it loops back around to the first user. After restoring the state of the user's process the kernel will service the I/O task that user process had originally requested, and return to let that user process run for a little while again. So all of the other user processes get their chance to run while one is waiting on data, and each process makes sure to allow the others a chance to run for a while when they are in the middle of running their own program.

I was able to throw together a quick proof of concept using the EASy68K simulator. What followed was days of catching all of the tiny mistakes I made, such as saving register A0 to the memory location reserved for register A1, overwriting the value previously saved for A1 and effectively losing both in the process — an error which resulted in BASIC printing only the first three characters of its startup header followed by a long string of null characters.

Debugging was tricky. I was starting from the bottom. No standard library, no existing structure or frameworks to rely on. The kernel process relied on the very same registers the user programs were using. Any changes to register contents by the kernel would affect the user processes. I ended up adding assembly macros to print short statements and register contents to the kernel console to try to get some insight into what was happening. I was able to track when registers came out of the user context save/restore process different than when they went in to find where I had bugs in that process.

This was a challenging project resulting in nearly a thousand lines of very low-level 68k assembly code, all of which I wrote and rewrote multiple times before figuring everything out. I've written small pieces of assembly code over the years, but none which required such deep dives into the CPU documentation to discern fine details of how the chip operates. I got there eventually though and now I have an 8MHz 68030 homebrew computer with 2MB of RAM that can run four BASIC programs simultaneously.

I'm going to need more terminals.

I’m downloading shapefiles (basically geographic files, in this case the polygons of every country) for a mapping project I’m doing and while most countries have an ISO code column in their file (which is a 2 letter abbreviation of their country name), Canada, the UK, and the US do not. The US doesn’t even have a country column, it just listed the states. Now these are official shapefiles made by the vendor of the software I’m using (Esri, which is one of if not the dominant global distributor of mapping software) and are treated as the authoritative copies. Like if you wanted to download the outline of the US and all its states you would download Esri’s copy of it. And the reason I noticed this discrepancy is because I’m trying to combine individual country files to a global world file and I first had to edit the US & UK & Canada shapefiles and manually add in their ISO codes so they would join the world file properly. Notably countries like Argentina already have country & ISO code embedded in its shapefile.

And what I’m taking away from this is that there is an epistemic assumption happening where western countries can stand alone - they do not need to be combined or compared with other countries, they are complete units that constitute their own global file. Their data lack an “international character,” they are not set up for comparison or combination with other country data. The assumption being made by excluding these (extraordinarily trivial and easy to include) datapoints is that the only reason you would be downloading shapefiles for the US or Canada is to study these countries in isolation, while countries in the Global South are structured to accommodate the act of comparison

Out of curiousity, how did you get into doing this sort of computer work? Especially more low level stuff. :]

How can other people get into it / what would you like to see people make in the future in this area?

- Aspiring Programmer

I was an extremely poor kid, in middle school I learned about piracy which led to me getting into FOSS software for media conversion so I could load a bunch of media onto my psp. A short time later I learned about cfw, custom firmware, for psps when I was trying to figure out how pirating games for the system worked, that led to my first hardware hacking, at the time you needed to make a "magic battery" in order to save money on hacking the system which luckily for me I was able to do with a busted battery. That was really my big start because it was so exciting to be a poor kid with access to tons of games and media all of a sudden. Since then I've been very interested in firmware work and embedded systems, though I definitely didnt know thats what it was at the time.

For getting into software/hardware hacking/programming in a similar way I'd seriously recommend getting a cheap SBC, something like a Raspberry Pi Zero or just a Raspberry Pi is a good place to start especially since there are tons of projects for those boards that you can hack on and tons of very useful programs like pi-hole which does DNS ad blocking.

As to what I'd like to see people do: more projects dealing with media on these kinds of systems, video djing, glitch art, etc, because usually you're limited to something like VLC for media.

[kyokosasagawa]

I started writing "4 srs" this month and I like how free and accessible writing is, so I'm recommending free software I've experimented with that might help people who want to get into the hobby!

“Specifically Created for Writing Stories”

-------------------------------

Manuskript – Story organizer / word processor. Has an outliner and index card function, along with distraction free mode. Lets you switch between different templates such as a non-fiction mode or a short story.

Bibisco – Novel writing software that includes writing goals, world-building, distraction free mode, and a timeline.

“I Just Want to Write”

---------------------------

LibreOffice – Microsoft 365 alternative, but free! LibreOffice Writer is what I wrote this tumblr post in before I posted it. Also if you copy & paste the text into the Rich Text Editor on AO3, it seems that it actually converts it properly. Nice! No need for scripts.

Note-Taking

-------------------------------

Zim Wiki - note taking application that is very, very lightweight (1.1mb). It functions with a tree structure, so I’d personally recommend it for world-building and character bios. There are built-in plugins that also turn it into a good software for task management (it even has a article on how to use it for GTD) and journalling. See also: CherryTree (2mb), which is a more outdated-looking app, but functions similarly.

Obsidian MD – The Big Boy. markdown note editor that has been adopted by personal knowledge management fans---if it doesn’t do something you want it to do, just look in the community plugins to see if someone has already done it. Some unique non-word processing related usages I’ve found is the ability to create a table of contents dashboard, a image gallery for images, embedding youtube videos and timestamping notes, so forth.

Logseq – A bullet point based markdown note editor that also has PDF annotations, Zotero integration, flashcard creation, and whiteboards. Best used for outlining projects due to the bullet point structure.

Joplin – A modern app comparable to Zim Wiki, it’s basically just a note-taking software that uses folders and tags to sort easier. Looks prettier than Zim Wiki and Cherry Tree

Notion – An online-only website that allows usage of different database types. Free for personal use. Note: I dislike the AI updates that have been making the app lag more. I prefer the others on this list.

Mind Maps

-------------------------------

Freeplane – So much goddamn features, including a ton of add-ons. Looks somewhat ugly, but it works for anyone willing to spend a while learning how to use it.

Mermaid – Text-based diagram creator. Can be used in apps like Joplin, Notion, and Obsidian.

Obsidian’s Canvas – A core plugin for Obsidian, it deserves its own mention in that it allows you to create embedded notes of the mindmap nodes. Thus, if you want to create a 20-page long note and have it minimized to the size of a penny on the mindmap, you could.

Other Things That Might Be Of Interest

Syncthing - A free software that allows you to sync between two or more computers. Have a desktop but also laze around on a laptop in bed, coming up with ideas?? This is your buddy if you don't want to use a online software.

[moose-mousse]

Finally fucking happened! Straight up stared at the boss with my mouth open while he was telling me something. I was saying we need to turn compiler optimization from the weird 01 with extra restrictions to 03. Functions that needs lower can then specify that with #pragma statements. But since those can only LOWER the compiler optimization we need it set to max per default. Boss then told me that we can never increase the compiler optimization level BECAUSE THEN THE COMPILER SOMETIMES CREATES WRONG MACHINE CODE!!! ... there is a limit... on how easy the code I can write I can write code... based on incompetence... Fuck Renesas micro-controllers! And screw my workplace for not starting to move to other micro-controllers the second they realized this!

No_inline means that any function I write will incur the cost of calling the function when the production code runs Normally I can break everything down into tiiiiny functions. 20 lines of code max. Everything is just... SO easy to read, understand, test and modify. And I can write them so they always get optimized away But nope. Cannot do that on an embedded system with no_inline Have to write giant impossible to read piece of shit function with 3-10 levels of abstraction jumps in them. Good luck you poor barstard that have to read my code later. Because I am now on another project. But it is taking a long time for some reason, because the code is unreadable. Anyway, good luck understanding my unreadable code! And then the boss claims we don't have money to change microcontrollers. And I am claiming, we cannot fucking afford to NOT pay for different micro-controllers. Software costs MILLIONS of dollars to develop. We are pissing MILLIONS out the window... So we can save several thousand dollars... Just... "Headdesks"

From Retro Roots to Modern Marvels: The Rebirth of the Pirate Menu Aesthetic

Ahoy, Nostalgia!

If you were a computer geek in the 80s or 90s, you probably remember the thrill of booting up a freshly acquired piece of software and being greeted by a "pirate menu." These were no ordinary start screens; they were vibrant, animated showcases, often accompanied by chiptune music, that hackers and crackers used to flaunt their digital prowess. These menus were as much a demonstration of skill as they were a distribution method for cracked software and games. It was a unique blend of artistry and rebellion, a way to connect with like-minded individuals in a pre-internet world.

The aesthetics of these pirate menus were distinctive and unforgettable. Neon colors, pixel art, and scrolling text formed the backbone of their visual appeal. They were DIY masterpieces, created in bedrooms and basements, meant to dazzle and entertain. Beyond their flashy exteriors, these menus communicated messages, credits, and even embedded jokes, forming a subculture that was as much about the community as it was about the content.

Shikantaza Art: Reviving the Rebel Spirit

Fast forward to today, and the digital nostalgia is real. Shikantaza Art has tapped into this rich vein of retro coolness, bringing the pirate menu vibe into the modern art world. By blending old-school aesthetics with contemporary design, Shikantaza is crafting pieces that evoke the same sense of wonder and excitement that those old pirate menus did. The work is a fusion of pixel art and modern graphics, often featuring animated elements and interactive components and linking to original works by consent and with collaboration of their creators.

We're not just creating art, and we're not just showcasing art; we're reviving a movement, a culture, and a way of connecting with audiences that feels both fresh and familiar.

THE FAEWAVE MENU Project: An Ode to the Past, A Beacon for the Future

Enter the FAEWAVE MENU project, our latest brainchild aiming to capture the spirit of the pirate menu era. This project is a digital platform that curates art, music, and independent video games, presenting them with the same visual flair and rebellious spirit of the old-school pirate menus. FAEWAVE MENUS are like stepping into a time machine that propels you forward, blending nostalgic aesthetics with cutting-edge content.

The project doesn’t just mimic the look and feel of the past; it harnesses it to create a community-driven space where creators can share their work in a visually engaging way. The menus are interactive, featuring music tracks, games, and art showcases that harken back to the days of floppy disks and CRT monitors. Yet, they are designed for the digital age, accessible from any desktop device with an internet connection.

FAEWAVE MENUS are more than a project; it’s a movement that resonates with both the old guard who lived through the original pirate scene and the new generation discovering its charm for the first time. It’s a testament to the timeless appeal of creative rebellion and the power of digital art to bring people together.

Check out THE FAEWAVE MENUS so far...

[quacheta]

So a few months ago, there was at least one (1) person who got permission to, and started, the project of bookbinding AmevelloBlue's The Ghost in the Shell. And when they tried to print it, it was like 700-800 pages. Which is... a lot.

So I figured, since (1) I also love Ghost in the Shell, (2) I do typesetting semi-professionally, and (3) why the heckers not, I could probably get it down to a more reasonable size.

And I did. And then AmevelloBlue gave me permission to share it here, so.

The Drive Folder With All the Files.

File-specific information below. :)

(Please, for the love of Donnie's banana pancakes, read it. I am trying to answer as many technical questions in advance as I can, so people don't get overwhelmed or confused or frustrated.)

(But also it is a LOT of information, so if you need clarification please ask. This is for to be fun! Not scary!)

There are three parts.

GitS.p8: This is the straight PDF export, done in pages and not spreads. That means each page is its own page (a spread has 2+ to a page) and the pages are in order. If you want a pretty PDF to read on a device, this is what you want. If you want to run it through your own imposition software, this is also what you want.

GitS.p8_typeset: This is the imposition. That means the pages have been rearranged into signatures and spreads for bookbinding. There are 16 pages, or 8 spreads, or 4 sheets of paper (printed double-sided) to each signature. Each signature gets stacked, folded into a booklet, and then stacked on top of the next signature for sewing the book block. THIS IS THE WHOLE BOOK. If you want ONE file to send to the printer, in one straight run, this is what you want.

signatures (folder): These are INDIVIDUAL SIGNATURES. That means each signature is a separate file. If you want to do a test print of a single signature, this is what you want. If you want to run different signatures through different printers, this is what you want. If you want to do this piecemeal for any other reason, this is what you want.

(The last three signatures are three sheets of paper, not four. This is for the sake of balancing page count against structural integrity in the bound book.)

Why would you want different printers, you ask?

Because color printing is expensive. And I used color in the typeset.

The entire thing is designed to still be readable (and pretty!) in a regular, black-and-white printer. Because I wanted this to be accessible to everyone, not just people who can afford color printing. But if you want to split it, and send the signatures-with-colored-bits to a color printer, and save money by NOT sending the whole book, these are the signatures with colored bits:

0, 5, 7, 11, 13, 14, 25, 26, 28, 35

And if that's too many pages still, here are the signatures with the most important colored bits (i.e., the title pages and the illustrations):

0, 7, 35

All of the files are PDFs. All of them, specifically, are PDF/x-1a(2003), which means the color profile is CMYK only and all the fonts are embedded. So nothing should go screwy-whompus when you download it or send it to the printer.

TRIM SIZE: the pages are 5x7.5. This is (1) to allow printing on letter-sized paper more easily, and (2) to also allow for trimming of the book block without screwing over the margins. The imposition and the signature files have trimming / cutting guides (the little lines) for your convenience.

There are 36 signatures total, or 560-something pages (less than 200 sheets of paper, before folding, if printed double-sided). This is still a big book. Big enough that you will need to know about spine swell, and possible rounding and backing, if you decide to do the binding. Please keep that in mind as you plan your project.

EPUB: some people like to convert PDF book files to ePUBs for eBook reading. Due to how I designed the typeset, this is not going to be pretty if you try it with these. I am currently in the final stages of making the eBook for GitS, and will upload the ePUB to the drive folder as soon as it's done. It will not have the pretty background / border illustrations of the print file, but it will be neat and tidy and include the pretty title pages.

I... think that's everything?

Configuring Zephyr: A Deep Dive into Kconfig

We presented The Zephyr Project RTOS and illustrated a personal best practice for beginning with "Zephyr" in an earlier blog post. A custom West manifest file is a great way to guarantee that your code is always at a known baseline when you begin development, as you saw in that blog post. Following the creation of your custom manifest file and the establishment of your baseline repositories using West, what comes next in your Zephyr journey?

Enabling particular peripherals, features, and subsystems is one of the first steps in putting embedded software into practice. Some MCU manufacturers, like STM32, Microchip, and TI, have tools in their IDEs that let developers add subsystems to their codebase and enable peripherals in their projects. These tools, however, are closely related to the MCUs that the vendors sell. Applying these tools' functionality to other MCUs is challenging, if not impossible.

However, we can enable a specific MCU subsystem or feature using a vendor-neutral mechanism provided by The Zephyr Project RTOS. For people like me who don't like GUIs, this mechanism can be used with a command line. The name of this utility is "Kconfig." I'll go over what Kconfig is, how it functions, and the various ways we can use it to incorporate particular features and subsystems into our Zephyr-based project in this blog post.

WHAT IS KCONFIG?

Kconfig is still utilized today as a component of the kernel compilation process, having been initially created as part of the Linux kernel. Kconfig has a particular grammar. Although fascinating, the specifics of how Kconfig is implemented in the Linux kernel are outside the purview of this blog post. Alternatively, if you're interested, you can read my article here: (https://www.linux-magazine.com/Issues/2021/244/Kconfig-Deep-Dive), which walks through the Kconfig source code. However, after seeing an example, it's simple to become familiar with the format of a "Kconfig"—the slang term for a specific configuration option. The Kconfig system consists of three primary components.

First, there is the collection of Kconfig files scattered across different OS codebase directories. For example, if we look under "drivers/led" within the Zephyr codebase, we see a file named Kconfig with the following contents:  menuconfig LED     bool "Light-Emitting Diode (LED) drivers"     help      Include LED drivers in the system configurationif LED...config LED_SHELL    bool "LED shell"    depends on SHELL    help      Enable LED shell for testing.source "drivers/led/Kconfig.gpio"...endif # LED

Using the if statement, the line that begins with "menuconfig" tells the Kconfig system that "LED" contains a number of feature options that are only visible if the "LED" feature is enabled. The user can then activate the "LED_SHELL" option if the "LED" feature is enabled. The result of this configuration option is a Boolean, which determines whether this feature is enabled or disabled, as the line that follows shows. If a configuration option refers to a particular configuration parameter, the result can also be an integer in addition to a Boolean. The line that starts with "depends" indicates that in order for the "LED_SHELL" feature to be visible, the "SHELL" feature needs to be enabled. As a result, only after the "LED" and "SHELL" features have been enabled will the "LED_SHELL" feature become visible. A more detailed explanation of the feature can be found in the two lines that begin with "help". Last but not least, the final line before the "endif" lets us refer to additional Kconfig files, which aids in classifying components. As though they were copied and pasted, the features of the referenced file are present in the current file. It is crucial to remember that the path to "source" comes from the Zephyr codebase's root.

HOW SHOULD YOU USE KCONFIG?

A collection of applications that enable users to enable or disable the features listed in all Kconfig files make up the second component of the Kconfig infrastructure. Zephyr provides a Visual Studio Code extension that enables users to carry out this task with a graphical user interface. For command line enthusiasts like myself, the VS Code extension provides an alternative to utilizing a graphical user interface. In order to configure Zephyr appropriately, the extension can accept a file, which is the final component of the Kconfig infrastructure and contains a set of configuration options that can be turned on or off. The following snippet shows an example. CONFIG_BT=yCONFIG_BT_PERIPHERAL=yCONFIG_BT_GATT_CLIENT=yCONFIG_BT_MAX_CONN=1CONFIG_BT_L2CAP_TX_MTU=250CONFIG_BT_BUF_ACL_RX_SIZE=254

There is nothing complicated about the file format. "CONFIG_" appears at the start of each line, and then the configuration option's name. After the "=" symbol, the line either ends with a "y" to activate the feature or a "n" to deactivate it. In the example above, we configure the stack parameters and activate the Bluetooth stack in Zephyr along with specific stack features. "prj. conf," which contains user-defined features, is the default file in the majority of Zephyr-based applications.

 

CONCLUSION

The Zephyr Project RTOS provides a robust, vendor-neutral mechanism called the Kconfig infrastructure that allows us to fully configure our entire application. It can be used to control particular subsystems and peripherals within the MCU in addition to turning on or off individual stacks within the RTOS and setting configuration parameters.
