This enumeration provides information about the ΩCP instructions.

The ΩCP Code Format

A ΩCP Program consists of a set of instructions. The instructions are stored in words of the length of 4 bytes (of 8 bits each). Each instruction is determined by an op code of one byte. The instruction can have 0 to 2 arguments. Any argument is at most 3 bytes (24 bits) long.

An instruction without arguments has the following layout:

8 bit 24 bit
op code unused

An instruction with one argument has the following layout:

8 bit 24 bit
op code argument 1

An instruction with two arguments has the following layout:

8 bit 24 bit
op code argument 1
unused argument 2

The ΩCP Programming Model
