RISCV simulator

Lab for "Computer Organization and Achitecture" course of PKU
Support RV64I instruction set with a 3 stage pipline implemented by using C
Temporarily the project do not support interrupt including syscal and Link library
The ELF part use opensource code at https://github.com/macmade/ELFDump/tree/master/ELFDump

There 2 modes you can choose:

1. Single Step: set CFLAG = -DSINGLE in Makefile and make. the commands are as follow:
   'c'(continue) run one instruction
   'r'(rigisters) print all rigisters
   'g'(go) keep running untill end of "main" section
   'm'(memory) print memory. Type as fomat "offset width", width will be ilegal except 1,2,4,8 Bytes

2. Pipeline: set CFLAG = -DPIPE and make

The RISCV program is compiled by RISC-V Tools, you can use following command to compile:
riscv64-unkown-elf-gcc -Wa,-march=rv64i -o filename filename.c or riscv64-unkown-elf-gcc -Wa,-march=rv64g -o filename filename.c (for rv64M instructions)

To run this project, you need:
make
./riscv filename
