Hi, I am analyzing write-through cache's behaviour. As far as I know, MARSS's write-through cache sends update messages to lower level two times. First it sends update message in handle_interconnect_cb function, then in cache_access_cb in cache hit case. I think first message is enough to update lower level caches. Why does it need to send update message two times? Is there any special reason or can I just comment out the code that sends update message in cache_access_cb (cacheController.cpp:592-596)?
Thanks, Hanhwi
