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

[Jason Lowe-Power via gem5-users]

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=XTIrVBb86aM&ab_channel=JasonLowe-Power for
more information.

Cheers,
Jason

[gem5-users] L2 or L3 cache interface

[Fengze Yu via gem5-users]

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
