Emulate 32-Bit and 64-Bit RISC-V in the Browser with Asami’s Open Source Rvemuriscv.org4 points·by d0iasm·há 6 anos·0 comments
d0iasm·há 6 anos·discussThe main difference between them is the number of instructions are supported. Rvemu supports RV64GC, while rvemu-for-book will support RV64I and instructions that xv6 uses (e.g. mul).Also rvemu will support a device tree but rvemu-for-book won't.
d0iasm·há 6 anos·discussThanks for your interest! I'm an author of this book. This book is very beginning as you mentioned and I'm still working on it.I already succeeded to run xv6 in my RISC-V emulator and wrote a blog post "Made a RISC-V Emulator Running Xv6": https://d0iasm.github.io/blog/risc-v/2020/04/03/xv6-on-my-ri...I have 2 different RISC-V emulators and its goals are different:rvemu (https://github.com/d0iasm/rvemu): Can run xv6. It's trying to support Linux and make it faster in the future.rvemu-for-book (https://github.com/d0iasm/rvemu-for-book): Reference implementation for the book. Simpler than original one.
Also rvemu will support a device tree but rvemu-for-book won't.
