Supported Instructions

The instruction set implemented in this processor was based on this MIPS reference sheet.

Note: This CPU currently does NOT support floating point operations.

* The syscall instruction has a move $k0, $ra instruction inserted prior to it by the pre-processor. This is done to allow for syscall to preserve the value in $ra, since syscall acts similarly to a jal instruction; despite the convention placing the responsibility of preserving the content of $ra on the callee. Future improvements may remove the need for this additional instruction's insertion.
