Hi,
I am using MESI_CMP_directory protocol. I would like to change the cache block
size in L1 cache and L2 cache to 1 word to simplify some techniques which I am
experimenting on.
For the Classic Memory System, configs/common/CacheConfig.py file sets the block
sizes of L1 and L2 caches. But I wasn't able to find the places to modify for
Ruby Memory System.
In src/mem/ruby/system/Cache.py, Ruby Cache class sets start_index_bit which is
related to the cache line size. Is this the one to be modified?
regards,
Prasanth
There is an option for specifying the cacheline size, namely,
cacheline_size. It defaults to 64 bytes. You can set it on the command
line.
