My implementation of the Little Man Computer. My friend inspired me to write an implementation of this for academic purposes, and I had a joy writing it.
I finished the first implementation in 2 days (really one day had I started early in the morning). I intend to make a few improvements over time.
lmc can execute code assembled with lmasm. I've included a test program
with this software. You can assemble it like so:
$ lmasm square.lma square.lexe
This will create the binary program square.lexe which lmc understands.
$ lmc square.lexe
This test program will square any number you input. Input 0 to quit. Note
that the LMC can only handle numbers up to 999, so any number higher than 31
will overflow and give an incorrect result, but this is a limitation of the
system.
