Data Cache Simulator

About The Project​

This program simulates the behavior of a data cache. The program reads a trace of references from standard input and produces statistics about the trace to standard output. The trace config allows you to configure the simulator program. With the trace config you can modify the number of cache sets, the number of lines within each set (associativity level), and the size of a cache line in bytes. It also gives you useful statistics like the hit/miss ratio, number of total access, etc.

Example Trace.config File​

Number of sets: 8  
Set size: 1  
Line size: 8

Trace of References​

The trace of references are read from stdin and have the following format:
<accesstype>:<size>:<hexaddress>

<accesstype> can be the characters R (which indicates read access) or W (which indicates write access).
<size> is the size of the reference in bytes.
<hexaddress> is the starting byte address of the reference expressed as a hexadecimal number.
