This is a RISC-V emulator for the RV32I architecture, based on TinyEMU and stripped down for RV32I only.
Requires libelf-dev:
$ sudo apt-get install libelf-dev
How to compile it:
$ gcc -O3 -Wall -lelf emu-rv32i.c -o emu-rv32i
or
$ make emu-rv32i
Passed RV32IC compliance tests from https://github.com/riscv/riscv-compliance
-
Must install the risc-v toolchain
-
Run RV32I compliance tests. Assume
emu-rv32i
in$PATH
environment variable.
$ git clone https://github.com/riscv/riscv-compliance
$ cd riscv-compliance
$ make RISCV_PREFIX=riscv-none-embed- RISCV_DEVICE=rv32i TARGET_SIM=emu-rv32i variant
- Run RV32IMC compliance tests.
Assume
emu-rv32i
in$PATH
environment variable.
$ git clone https://github.com/riscv/riscv-compliance
$ cd riscv-compliance
$ make RISCV_PREFIX=riscv-none-embed- RISCV_DEVICE=rv32imc TARGET_SIM=emu-rv32i variant
Compiling and running simple code:
$ make test1
then
$ ./emu-rv32i test1
Hello RISC-V!
