The cachesimulation from adhnguyen

cachesimulation's Introduction

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

                 total CPI 4.26 
                 average memory access time 8.54 cycles 
                 
        dirty evictions 60540 
        load_misses 523277 
        store_misses 30062

cachesimulation's Issues

Cannot compile on Ubuntu

$ cc -lm -o cachesim cache.c
/tmp/ccyFUIAD.o: In function `main':
cache.c:(.text+0xacb): undefined reference to `log'
cache.c:(.text+0xb1d): undefined reference to `log'
collect2: error: ld returned 1 exit status

running without arguments

Just wanted to let you know that running without arguments isn't handled, and causes the terminal to freeze. Might want to put a handle in for if argv is empty.
