We have a fantastic update for you! FPGAs, when optimized at a granular level for specific algorithms, can deliver performance far beyond traditional CPU-based solutions. With their efficiency and parallelism, FPGAs are game-changers for accelerators, and we’re here to prove it.

15x the Performance at Just Twice the Cost of an RPi 5 While Consuming Only 12 W of Power!

We’ve developed a custom SHA-256 FPGA IP running at 100MHz, executing 66 clock cycles per hash, with 37 parallel instances. This results in a staggering 57.6 MH/s for SHA-256-based applications.

In comparison, a highly optimized Raspberry Pi 5 reaches a maximum of 3 MH/s—meaning we deliver 15x better performance for only 2x the price!

But here’s what makes it even more impressive: the entire system operates at just 12W, making it remarkably power efficient. While CPUs struggle with power-hungry hashing operations, our optimized FPGA-based approach delivers breakthrough efficiency without compromising speed.

How Does It Work?

At the heart of our system is Vaaman, featuring a 6-core ARM processor running Linux. We utilize Rah, our custom interconnect protocol, to establish high-speed communication between the CPU and FPGA.

For benchmarking, we implemented a standard Bitcoin mining algorithm on our platform. On the FPGA side, our highly optimized SHA-256 IP continuously processes hashes in parallel. Once a valid hash block is found, it is seamlessly transferred back to the CPU—delivering unprecedented efficiency in cryptographic computations.

Seamless Integration for Vaaman Users

For every Vaaman user, we are providing an easy-to-use framework to benchmark this accelerator and integrate SHA-256 into their own applications.

With simple APIs (available in C/C++ and Python), users can harness FPGA-accelerated cryptographic processing without complex development overhead.

What’s Next?

Stay tuned as we continue to push the boundaries of reconfigurable computing, FPGA acceleration, and high-performance cryptographic processing.

This is just the beginning!
