asm for mc cpu

Simple toy assembly to machine code compiler and cpu emulator.

---

This compiler is designed to work from command line, take single text file and produce binary or hexadecimal output.

Assembly Language Specification

Usage

Show help

$ asm-for-mc-cpu --help

Specify input file -i FILE

Specify output file -o FILE You can use file with extensions:

• .bit to produce text file with binary representation of each instruction and comments, example shown below.

0000: 0000 0000 0000 0000    Or r0,r0,r0
0001: 0011 0000 1000 1111    Ex.Cldi r8,r0
0002: 0000 0000 0010 0000    #0x0020
0003: 0011 0000 1001 1111    Ex.Cldi r9,r0
0004: 0000 0000 0100 0000    #0x0040

• .hex to produce text file with hexadecimal representation of each instruction.
• any other extension or lack of it will produce a binary file.

Compiling some file:

$ asm-for-mc-cpu -i my_file.asm -o compiled.bit

Run emulator window -e NUMBER_OF_RAM_CELLS will launch emulator window on compiled program with scrolable memory view, register content view. You should specify number of ram cells to allocate for the emulator.

Example usage:

$ asm-for-mc-cpu -i my_code.asm -e 128

Will show emulator window with 128 cells of ram:
