RISC-V emulator implementation in C

The specifications of the RISC-V instruction set architecture (ISA) can be found here. It's a simple ISA, containing just 37 instructions. The 0x5000 address serves the purpose of the memory mapped I/O, which means that a byte written to this address is written to stdout.

Structure

• risc-v_emu is the executable to run
• main.c contains all the source code
• main_debugging.c is the source code with printing statements for debugging (which are easily "turned on/off" by commenting out the respective trace macro)
• /AssemblerTestProgramm, /ProgrammEins and /ProgrammPrimzahlen contain the binaries needed to run the emulator.

Running the program

Run the program with the following command from the project root:

./risc-v_emu <instructions> <data>

where the 1st argument is the path to a binary with instructions and the 2nd argument is the path to a binary with data to write to and read from.
