how to add L2 cache

[M123040025]

hello,
how to modify the source code to simulation multi-level cache?

[EtDloaulDaol]

same question......
I don't understand the architecture of Ripes simulator...

by the way 如果你也是交大的同學要做final project的話可以一起嗎><

我也是要做bonus project可以來合作一下，雖然我不是交大的同學。

Have either of you done any work on this in the past 10 months?

Not as far as I am aware of.

A lot of the infrastructure for this has actually already been done, and is in Ripes already (work in this branch: c151bd7).

Specifically, you should be looking into the CacheInterface and the m_nextLevelCache-related variables. Some stuff is already in there, and some stuff is missing. Basically, what's needed are:

1. A way to add more cache levels in the GUI; one could imagine that multi-level caches are added via. new tabs in the gui (again, refer to the old branch since it already has some of that work https://github.com/mortbopet/Ripes/commits/n_caches/).
2. Once that is done, connecting that up to adding new m_nextLevelCaches, and propagating CacheInterface::access calls in-between caches whenever there is a cache miss.

Regardless, adding this change requires that you'll spend some time digging through and understanding the codebase, since it involves touching both GUI and simulator related things.

Hope that helps your further research!
