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!

"VHDL stands for ‘Very High Speed Integrated Circuit Hardware Description Language' "

pure poetry, the capitalization of letters not present in the acronym, the vagueness of "Very High Speed" (what makes something very high speed vs regular high speed?) . No explanation of where the missing letters went. And they say art and STEM don't mix

The Department of Electronics and Communication Engineering K.Ramakrishnan College of Technology, in association with the IEEE Student Branch, recently organized an insightful invited talk on “Demystifying FPGA Design: From Concept to Implementation.” Further, this event, featured Dr.M.Elangovan, Associate Professor, Department of Electronics & Communication Engineering, Government College of Engineering, Trichy. Moreover, nearly 122 third-year students from our department attended the session, actively participated, and greatly benefited from the expert insights shared.

High Performance FPGA Solutions

In today's rapidly evolving technological landscape, the demand for high-performance solutions is ever-increasing. Field-Programmable Gate Arrays (FPGAs) have emerged as versatile tools offering customizable hardware acceleration for a wide range of applications. Let's delve into the world of high performance FPGA solutions, exploring their key features, applications, challenges, recent advances, case studies, and future trends.

Introduction to High Performance FPGA Solutions

Designing high performance FPGA solutions requires expertise in hardware architecture, digital signal processing, and programming languages such as Verilog or VHDL. Optimizing performance while meeting timing and resource constraints can be challenging and time-consuming.

Optimization for Specific Tasks

FPGAs offer a high degree of customization, but optimizing performance for specific tasks requires in-depth knowledge of the application domain and hardware architecture. Balancing trade-offs between speed, resource utilization, and power consumption is essential for achieving optimal results.

Integration with Existing Systems

Integrating FPGA-based accelerators into existing hardware and software ecosystems can pose compatibility and interoperability challenges. Seamless integration requires robust communication protocols, drivers, and software interfaces.

Recent Advances in High Performance FPGA Solutions

Improved Architectures

Advancements in FPGA architecture, such as larger logic capacity, faster interconnects, and specialized processing units, have led to significant improvements in performance and efficiency.

Enhanced Programming Tools

New development tools and methodologies simplify the design process and improve productivity for FPGA developers. High-level synthesis (HLS) tools enable software engineers to leverage FPGA acceleration without requiring expertise in hardware design.

Integration with Other Technologies

FPGAs are increasingly being integrated with other technologies such as CPUs, GPUs, and ASICs to create heterogeneous computing platforms. This allows for efficient partitioning of tasks and optimization of performance across different hardware components.

celebrating fall with fletcher's checksum

This post originally appeared on my website.

why are checksums useful for fpga development?

Checksum functions are useful for error detection and data integrity. With respect to FPGA architecture development, a checksum can ensure the system is able to retain its state. For example, an FPGA programmed to behave like an AND gate should not start to act like an OR gate due fluctuations in voltage or temperature. Such problems may be caught by computing the checksum of the bitstream before configuring the FPGA, operating the device in the lab, and then extracting the bitstream and re-computing the checksum to ensure it has not changed.

The last two FPGAs that I worked on-with Indiana University's SAIL-IN Lab and the QuickLogic Corporation-used a scan chain configuration interface which lent itself well to bitstream verification via checksum. The scan chain acts like a serial shift register, stringing together all the configuration chain flip-flops in the FPGA fabric. As the bitstream flows through the head of the scan chain, one bit at a time, its checksum may be computed; and later re-computed as it flows out of the tail. For context, imagine a small, thirty-two flop scan chain and the corresponding bitstream, 0xdeadbeef. On the way in, the Fletcher's (32-bit) checksum will be 0xf13b. If the post-configuration checksum does not match, the engineers would know that there is an issue with the FPGA architecture.

Fletcher's checksum also produces check bytes (or a "tag"), which can be appended to the end of the original data, such that the new checksum of the data and the check bytes is zero. For the example bitstream 0xdeadbeef, the resulting check bytes are 0xd2f1. And the checksum of 0xdeadbeefd2f1 is 0x0.

fletcher's checksum in systemverilog

Based mostly on the Wikipedia entry for Fletcher's checksum, I produced a parameterized, three-state module which computes the checksum and check bytes of a data stream. The SystemVerilog closesly follows the below psuedo-code. For the Fletcher-32 checksum, data arrives as 16-bit half-words.

Eventually, I'd like to wrap it in a SPI interface and submit it to TinyTapeout, but for now here's the bare RTL. The most up-to-date code is also available on GitHub:
