D16 interpreter

This project is a mostly-complete emulator for the D16 cpu. Generating code to execute requires a working and up to date version of the d16 assembler.

Usage

Run ./run_d16i.py <assembler_output.bin>

For each instruction executed, the emulator will output the address, instruction type, flags, and the state of every register.

For example:

addr instr  : NZCV  r0   r1   r2   r3   r4   r5   r6   r7
0000 NOP    : 0000  0000 0000 0000 0000 0000 0000 0000 0000
0002 MOVB_R0: 0000  0000 0000 0000 0000 0000 0000 0000 0000
0004 ADDI   : 0100  0000 0000 0000 0000 0000 0000 0000 0000
0008 STI    : 0000  2000 0000 0000 0000 0000 0000 0000 0000
000c JMPI   : 0000  2000 0000 0000 0000 0000 0000 0000 0000
0010 AND    : 0000  2000 0000 0000 0000 0000 0000 0000 0000
0012 STOP   : 0100  2000 0000 0000 0000 0000 0000 0000 0000

Requirements

1. Ensure you have Python 3.5 and Tox installed and on your PATH.
2. Run tox to initialize the virtualenv and ensure that tests successfully complete.
3. Run source .tox/py35/bin/activate to make sure that python can find all dependencies.
