[gem5-users] Re: L2 or L3 cache interface

Hi Fengze, No, there is no defined interface between different levels of the cache in Ruby. Ruby is a "black box" in some sense, with input on the CPU side and output on the memory side. See https://www.gem5.org/documentation/learning_gem5/part3/MSIintro/ and https://www.youtube.com/watch?v=XTIrVB

[gem5-users] L2 or L3 cache interface

Hi  What is the interface between L1 and L2 cache in Ruby cache coherence model? Is there a clear defined interface, similar to the icachePort and dcachePort between CPU and memory, between different levels of caches in Ruby? Thanks in advance Fengze Yu ___
