Simulates a 64-bit, byte-addressable, write-allocate, write-back cache with sub-blocking and a victim cache. Accepts SPEC benchmark traces as input to simulate. On a read or write, sub blocks are fetched from the sub block of the access to the end of the block.
Run make to build the project. make clean removes built files.
| Flag | Use | Default |
|---|---|---|
| -C | Cache size = 2^C | 15 |
| -B | Bytes per cache block = 2^B | 5 |
| -S | (set associativity) Blocks per set = 2^S | 3 |
| -K | Bytes per sub block = 2^K | 3 |
| -V | Size of victim cache in blocks = V | 4 |
| -i | SPEC format input | stdin |
make clean
make
./cachesim -B 5 -V 4 -i traces/astar.trace
can also accept input from stdin:
./cachesim -B 5 -V 4 < traces/perlbench.trace
- Issues reading from files and stdin on OSx. About 1 in 20,000 inputs will not be correctly read on these systems.
