Works

This is a summary of what I have made since the second half of 2020.

CSVX

CSVX is an extension of CSV format. This extension allows you to use CSV as a spreadsheet. This is available as a library written in Rust.

CSVを拡張して、表計算できるようにするライブラリを作りました。https://t.co/7daaEXOv02にも公開しています。ぜひ使ってみてください！！https://t.co/1IW4yM42I7 https://t.co/lyhSNtUisa

Application

I have also published a web app using this library. The implementation uses Next.js and WebAssembly.

Self-made Processor (RISC-V Based)

I designed a RISC-V(RV32IM) based CPU. This prototype runs on DE0-CV board at 50 MHz¹.

6-stage instruction pipeline
Out-of-order execution
Simple 6-stage speculative execution
2-way superscalar

自作アウトオブオーダCPU完成しました！！！！！
7セグLEDで目視デバッグ、めっちゃ苦行だった...

ちなみに、簡易的な6段投機実行と、2-wayスーパースカラとかも搭載してます。https://t.co/IRT4TdhXwd pic.twitter.com/mevQX9YLJW
