yas simulation

This chapter focus on processor architecture and design a little simple
processor and yas — a assemble language — designed running on it.

you can access the
processor simulation code and simulation manual from csapp official site.

simulation code

simulator manual

I have saved the simulation code in directory chapter4/code/sim.

Highly recommend you read
the manual and README in code to know how it works and how to test yas code.

test

code directory: ./code

test way:

• assert means assert function from <assert.h>
• output means to watch code output to judge if it works right
• yas means using simulator test script to test simulator itself
