	Builds the Y86-64 tools

README
	This file

misc/	
	Source files for the Y86-64 instruction
	simulator yis, and the isa.c file that is used to compare outputs
    for the other simulators

seq/	
	Code for the SEQ simulator. This is provided as reference

pipe/	
	Code for the PIPE simulator. You will need to modify psim.c.

	Code for the CACHE simulator. You will need to modify cache.c.

pipe-cache/	
	Code for the PIPE with CACHE simulator. You will need to modify pcsim.c.

y86-code/
	Example .ys files from CS:APP and scripts for conducting
	automated benchmark teseting of the new processor designs.

ptest/
	Automated regression testing scripts for testing processor designs.
