adhnguyen / CacheSimulation

MIPS Cache Simulator in C. It will read an address trace (a chronological list of memory addresses referenced), simulate the cache, generate cache hit and miss data, and calculate the execution time for the executing program

1. Build the cache simulator.
 % cc -o cachesim cache.c -lm

2. Test the cache simulator.
 % gunzip -c traces/art.trace.gz | ./cachesim
 % gunzip -c traces/[name of trace] | ./cachesim [cachesim args]

 Example 1 
 
> gunzip -c traces/art.trace.gz | ./cachesim -a 1 -s 16 -l 16 -mp 30 
        Cache parameters: 
        Cache Size (KB) 16 
        Cache Associativity 1 
        Cache Block Size (bytes) 16 
        Miss penalty (cyc) 30
