grvemu

Go License

RISC-V emulator for CLI written in Go

For now, grvemu supports only rv32i.

grvemu can pass some riscv-tests and run c program. If you want to try them, you can use riscv-tools-and-tests-docker-for-grvemu.

Install

go install github.com/kinpoko/grvemu@latest

Usage

grvemu -h
RISC-V emulator for cli written in Go

Usage:
  grvemu [binary file] [flags]

Flags:
  -a, --arch string   architecture (default "rv32i")
  -d, --debug         debug mode
  -e, --eof uint32    end of binary
  -h, --help          help for grvemu
  -t, --test          display global pointer

grvemu's Issues

Any test cases?

Hello,

I am interested in RISC-V emulators for possible use in an embedded project and in particular, I am wondering about RV128 implementation to see what that might take to get working with the Risc-V 128-bit instruction set so as to be able to assess the much larger address space.

I was able to compile your code on my Windows 10 with Golang 1.19.3 and it seemed to run, but I did not have any test cases that I could find in your code to give it a try.

Ultimately, I would like to build out a binary tree implementation with 128-bit implementation, if possible.

Do you have any thoughts on this?
