Re: [gem5-users] Small entry table creation in gem5

[조해윤]

Hello.

I think it depends on the purpose of the table and modeling features.

For example,  let's look a cache tag modeling case.
BaseTags class (/mem/cache/tags/base.hh), which is a kind of table to store
tags, inherits the ClockedObject, because BaseTags needs to model the clock
latency.
However, Cacheset class (/mem/cache/tags/cacheset.hh), which is used in
BaseSetAssoc (it inherits BaseTags class), doesn't inherit any class.
Because, Cacheset is just a data structure, which doesn't model clock
latency.
The latency to access Cacheset (it sounds wired actually, because latency
is for tag access and Cacheset is subset of tag model) is modeled in
BaseSetAssoc class, which inherits ClockedObject.

[gem5-users] Small entry table creation in gem5

[Muhammad Avais]

Hi,

I want to create small table (256 entries) in gem5 that is accessed on each
cache miss and follows LRU replacement policy.

Can someone guide me how to do it? (Which classes i should use or inherit)

Many Thanks
