hi,

I'd like to ask question about OPENRISC cache.
Currently the cache is implemented as one-way , write-through.
If I change this to 2-way cache, will the performance be improved?
How much effort it will be?
Another thing is about cache write. The current implementation
of write-through will occupy more system bandwidth. How about change
to write-back? Any one have this plan?
A trade off is adding write fifo, will this improve a little bit?
Thanks.
