SPIM can read and immediately execute assembly language files. SPIM is a self-contained system for running MIPS programs. It contains a debugger and provides a few operating system-like services. SPIM is much slower than a real computer (100 or more times). How ever, its low cost and wide availability cannot be matched by real hardware!
An obvious question is, “Why use a simulator when most people have PCs that contain processors that run significantly ...
