In this post, I’ll explore the SuperH instruction set and its relevance today, along with a tool I created to navigate it.

A few years ago, I met some of the members of the team behind the development of the J-Core, a SuperH clone, and had some really interesting discussions with them. Using this resource, I created, for my own understanding, a JSON file and the dynamic table below to help me navigate and understand the SuperH instruction set. I also added J2-related instructions that were not present in the initial material. As I turn off my AWS account, I realized I could just share it via a GitHub page. Here is a bit more context about SuperH.
