WarFox Posted August 5, 2021 Share Posted August 5, 2021 A cool article I have been slowly working through between projects. The link is a guide to writing a virtual CPU. The design here is lc3, which was a purely academic design used for teaching students and as far as I am aware, no real hardware implementation. Once I fully work through this, I am toying with the idea of writing a virtual CPU for RISC-V or PowerPC/Power10. https://github.com/justinmeiners/lc3-vm Link to comment Share on other sites More sharing options...
cwade12c Posted August 5, 2021 Share Posted August 5, 2021 Impressive that the final code is about 250 lines of C. This looks intriguing, I'd love to see any progress you make on writing a virtual CPU. Link to comment Share on other sites More sharing options...
WarFox Posted August 5, 2021 Author Share Posted August 5, 2021 That may be a winter break project. I've love to target PowerPC, not the recent Power iterations. Reason being is that iBook G4 I have, I picked it up specifically to play with assembly on it and potentially write an OS for. Implementing the PPC ISA may make it a little easier to handle the assembly bits of an OS for that machine. Link to comment Share on other sites More sharing options...
