Hi All,
I am currently trying to understand the cache trace for L2. I don't quite
understand how the write request are handled. From the trace I can see
ReadReq and ReadExReq. They are either miss or hits. However, I don't see any
trace for 'writes' only see 'writebacks'. What are the meaning for the
following?
-writeback hits
-writeback miss
-writeback replacements
Assuming the caches are writeback and write allocate, the L2 cache should
not receive any write requests. When the L1 cache replaces a dirty
block, the L2 cache will receive a write back request.
