Options for submission, whichever is easier for you:
- Copy your source into this repo, or...
- Submit a PR for the Sprint Challenge from the
Computer-Architecture-One
repo you've been using all along.
Sprint Challenge:
Add the CMP
instruction and equal
flag to your LS-8.
Add the JMP
instruction.
Add the JEQ
and JNE
instructions.
Here is some code that exercises the above instructions. It should print:
