UNAmiga FPGA - Updating AmigaOS and Tools…

[kawaoneechan]

Hot take: far as I'm concerned, recreating an old system with an FPGA does not make it "not emulation".

You're still making the thing run on other, newer hardware. You're just not doing it in software. The FPGA is still just pretending very hard to be a SNES or what have you. The main difference is that there's not an entire operating system running underneath the emulator. It's not even running on the bare metal -- it is the bare metal, so there's a significant lack of overhead and with a good design input lag can be all but eliminated.

But it's still just an emulator.

After all, this

is not this

any more than this is

Now, you might argue seeing that SNES mainboard closeup that there's a one-chip SNES too and that doesn't look anything like that picture either. True. It's called a one-chip because they took all the component parts of the CPU and PPU pair, and stuck it into a single chip. Not reimplementing, but restructuring.

Throwback to last year, when I built this custom 9-bit computer from scratch using an FPGA board.

Why? Mostly to see if I could do it. I had the good fortune to be part of several hardware teams designing computers when I worked for Digital Equipment Corp, but never directly in the CPU group. So I wanted to try CPU design out for myself finally, and see if I remembered any of those classes from way back in college. (I didn't as it turned out, had to re-learn a bunch of stuff)

Why 9 bits? To be weird. And also, because it prevented me from reusing anything that already existed, and so it forced me to do many common things all over from ground zero, like creating my own VGA video driver circuits, designing a new (octal) instruction set, and writing a custom boot loader and assembler.

Anyway I got it to the point where the machine could display Mario, here he is in glorious 9-bit color!

OneAPI Construction Kit For Intel RISC V Processor Interface

With the oneAPI Construction Kit, you may integrate the oneAPI Ecosystem into your Intel RISC V Processor.

Intel RISC-V

Recently, Codeplay, an Intel business, revealed that their oneAPI Construction Kit supports RISC-V. Rapidly expanding, Intel RISC V is an open standard instruction set architecture (ISA) available under royalty-free open-source licenses for processors of all kinds.

Through direct programming in C++ with SYCL, along with a set of libraries aimed at common functions like math, threading, and neural networks, and a hardware abstraction layer that allows programming in one language to target different devices, the oneAPI programming model enables a single codebase to be deployed across multiple computing architectures including CPUs, GPUs, FPGAs, and other accelerators.

In order to promote open source cooperation and the creation of a cohesive, cross-architecture programming paradigm free from proprietary software lock-in, the oneAPI standard is now overseen by the UXL Foundation.

A framework that may be used to expand the oneAPI ecosystem to bespoke AI and HPC architectures is Codeplay’s oneAPI Construction Kit. For both native on-host and cross-compilation, the most recent 4.0 version brings RISC-V native host for the first time.

Because of this capability, programs may be executed on a CPU and benefit from the acceleration that SYCL offers via data parallelism. With the oneAPI Construction Kit, Intel RISC V processor designers can now effortlessly connect SYCL and the oneAPI ecosystem with their hardware, marking a key step toward realizing the goal of a completely open hardware and software stack. It is completely free to use and open-source.

OneAPI Construction Kit

Your processor has access to an open environment with the oneAPI Construction Kit. It is a framework that opens up SYCL and other open standards to hardware platforms, and it can be used to expand the oneAPI ecosystem to include unique AI and HPC architectures.

Give Developers Access to a Dynamic, Open-Ecosystem

With the oneAPI Construction Kit, new and customized accelerators may benefit from the oneAPI ecosystem and an abundance of SYCL libraries. Contributors from many sectors of the industry support and maintain this open environment, so you may build with the knowledge that features and libraries will be preserved. Additionally, it frees up developers’ time to innovate more quickly by reducing the amount of time spent rewriting code and managing disparate codebases.

The oneAPI Construction Kit is useful for anybody who designs hardware. To get you started, the Kit includes a reference implementation for Intel RISC V vector processors, although it is not confined to RISC-V and may be modified for a variety of processors.

Codeplay Enhances the oneAPI Construction Kit with RISC-V Support

The rapidly expanding open standard instruction set architecture (ISA) known as RISC-V is compatible with all sorts of processors, including accelerators and CPUs. Axelera, Codasip, and others make Intel RISC V processors for a variety of applications. RISC-V-powered microprocessors are also being developed by the EU as part of the European Processor Initiative.

At Codeplay, has been long been pioneers in open ecosystems, and as a part of RISC-V International, its’ve worked on the project for a number of years, leading working groups that have helped to shape the standard. Nous realize that building a genuinely open environment starts with open, standards-based hardware. But in order to do that, must also need open hardware, open software, and open source from top to bottom.

This is where oneAPI and SYCL come in, offering an ecosystem of open-source, standards-based software libraries for applications of various kinds, such oneMKL or oneDNN, combined with a well-developed programming architecture. Both SYCL and oneAPI are heterogeneous, which means that you may create code once and use it on any GPU AMD, Intel, NVIDIA, or, as of late, RISC-V without being restricted by the manufacturer.

Intel initially implemented RISC-V native host for both native on-host and cross-compilation with the most recent 4.0 version of the oneAPI Construction Kit. Because of this capability, programs may be executed on a CPU and benefit from the acceleration that SYCL offers via data parallelism. With the oneAPI Construction Kit, Intel RISC V processor designers can now effortlessly connect SYCL and the oneAPI ecosystem with their hardware, marking a major step toward realizing the vision of a completely open hardware and software stack.

Understanding FPGA Architecture: Key Insights

Introduction to FPGA Architecture

Imagine having a circuit board that you could rewire and reconfigure as many times as you want. This adaptability is exactly what FPGAs offer. The world of electronics often seems complex and intimidating, but understanding FPGA architecture is simpler than you think. Let’s break it down step by step, making it easy for anyone to grasp the key concepts.

What Is an FPGA?

An FPGA, or Field Programmable Gate Array, is a type of integrated circuit that allows users to configure its hardware after manufacturing. Unlike traditional microcontrollers or processors that have fixed functionalities, FPGAs are highly flexible. You can think of them as a blank canvas for electrical circuits, ready to be customized according to your specific needs.

How FPGAs Are Different from CPUs and GPUs

You might wonder how FPGAs compare to CPUs or GPUs, which are more common in everyday devices like computers and gaming consoles. While CPUs are designed to handle general-purpose tasks and GPUs excel at parallel processing, FPGAs stand out because of their configurability. They don’t run pre-defined instructions like CPUs; instead, you configure the hardware directly to perform tasks efficiently.

Basic Building Blocks of an FPGA

To understand how an FPGA works, it’s important to know its basic components. FPGAs are made up of:

Programmable Logic Blocks (PLBs): These are the “brains” of the FPGA, where the logic functions are implemented.

Interconnects: These are the wires that connect the logic blocks.

Input/Output (I/O) blocks: These allow the FPGA to communicate with external devices.

These elements work together to create a flexible platform that can be customized for various applications.

Understanding Programmable Logic Blocks (PLBs)

The heart of an FPGA lies in its programmable logic blocks. These blocks contain the resources needed to implement logic functions, which are essentially the basic operations of any electronic circuit. In an FPGA, PLBs are programmed using hardware description languages (HDLs) like VHDL or Verilog, enabling users to specify how the FPGA should behave for their particular application.

What are Look-Up Tables (LUTs)?

Look-Up Tables (LUTs) are a critical component of the PLBs. Think of them as small memory units that can store predefined outputs for different input combinations. LUTs enable FPGAs to quickly execute logic operations by “looking up” the result of a computation rather than calculating it in real-time. This speeds up performance, making FPGAs efficient at performing complex tasks.

The Role of Flip-Flops in FPGA Architecture

Flip-flops are another essential building block within FPGAs. They are used for storing individual bits of data, which is crucial in sequential logic circuits. By storing and holding values, flip-flops help the FPGA maintain states and execute tasks in a particular order.

Routing and Interconnects: The Backbone of FPGAs

Routing and interconnects within an FPGA are akin to the nervous system in a human body, transmitting signals between different logic blocks. Without this network of connections, the logic blocks would be isolated and unable to communicate, making the FPGA useless. Routing ensures that signals flow correctly from one part of the FPGA to another, enabling the chip to perform coordinated functions.

Why are FPGAs So Versatile?

One of the standout features of FPGAs is their versatility. Whether you're building a 5G communication system, an advanced AI model, or a simple motor controller, an FPGA can be tailored to meet the exact requirements of your application. This versatility stems from the fact that FPGAs can be reprogrammed even after they are deployed, unlike traditional chips that are designed for one specific task.

FPGA Configuration: How Does It Work?

FPGAs are configured through a process called “programming” or “configuration.” This is typically done using a hardware description language like Verilog or VHDL, which allows engineers to specify the desired behavior of the FPGA. Once programmed, the FPGA configures its internal circuitry to match the logic defined in the code, essentially creating a custom-built processor for that particular application.

Real-World Applications of FPGAs

FPGAs are used in a wide range of industries, including:

Telecommunications: FPGAs play a crucial role in 5G networks, enabling fast data processing and efficient signal transmission.

Automotive: In modern vehicles, FPGAs are used for advanced driver assistance systems (ADAS), real-time image processing, and autonomous driving technologies.

Consumer Electronics: From smart TVs to gaming consoles, FPGAs are used to optimize performance in various devices.

Healthcare: Medical devices, such as MRI machines, use FPGAs for real-time image processing and data analysis.

FPGAs vs. ASICs: What’s the Difference?

FPGAs and ASICs (Application-Specific Integrated Circuits) are often compared because they both offer customizable hardware solutions. The key difference is that ASICs are custom-built for a specific task and cannot be reprogrammed after they are manufactured. FPGAs, on the other hand, offer the flexibility of being reconfigurable, making them a more versatile option for many applications.

Benefits of Using FPGAs

There are several benefits to using FPGAs, including:

Flexibility: FPGAs can be reprogrammed even after deployment, making them ideal for applications that may evolve over time.

Parallel Processing: FPGAs excel at performing multiple tasks simultaneously, making them faster for certain operations than CPUs or GPUs.

Customization: FPGAs allow for highly customized solutions, tailored to the specific needs of a project.

Challenges in FPGA Design

While FPGAs offer many advantages, they also come with some challenges:

Complexity: Designing an FPGA requires specialized knowledge of hardware description languages and digital logic.

Cost: FPGAs can be more expensive than traditional microprocessors, especially for small-scale applications.

Power Consumption: FPGAs can consume more power compared to ASICs, especially in high-performance applications.

Conclusion

Understanding FPGA architecture is crucial for anyone interested in modern electronics. These devices provide unmatched flexibility and performance in a variety of industries, from telecommunications to healthcare. Whether you're a tech enthusiast or someone looking to learn more about cutting-edge technology, FPGAs offer a fascinating glimpse into the future of computing.

check out my lil fpga microcomputer project ive put way too much time into it and its nowhere near done

it's part of my wider 'NotSoTiny' project, a 16 bit ISA taking after the 8086. The name comes from the original plan to use a TinyFPGA BX, but it never shipped so I switched to a FireAnt.

on the left side with the mess of jumpers is 1 MB of ram (the fpga has ~15kB onboard), and on the right are a couple of SPI driven displays. The TFT up top has a microSD card slot on its SPI bus too. Some buttons will go in the center.

now to just make the actual cpu...

there're three github repos, one for the architecture, which has the documentation, emulator, and assembler, one for the HDL side of this project, and one for a compiler for a language i made for the purpose of making a compiler (at least when i get around to putting it on github)
