Re: [gem5-users] Implementing tag-less cache architecture only for the last level cache

Hi jason, Apologies for a naive understanding of your tutorial, I just thought the cache that you designed can be the design of tag-less caches, since there were no tags used in your implementation. Apparently, I'm understanding is completely wrong. I need a tagless architecture for the cache to

Re: [gem5-users] Implementing tag-less cache architecture only for the last level cache

Hi Varun, The SimpleCache is just a starting point. It isn't at all a realistic model! It's an example to show you how to use gem5 ports. It will not be able to handle most realistic situations (e.g., being used as anything other than a single core L1 cache). You can take this code as a starting

Re: [gem5-users] Implementing tag-less cache architecture only for the last level cache

Hi Jason, I went through the tutorial and understood quite a bit of it. What I understood is that, there is no usage of tags in the implementation, just an unordered map. So I thought with some changes in the latencies, I can create a tagless blocking cache. Is this a correct starting point in imp

Re: [gem5-users] Implementing tag-less cache architecture only for the last level cache

Hi Jason, So I should understand how to create new objects in the simulator and try to create a new object for tag-less cache. I will go through the book and see if I get any leads in this regard. I will update on this in a week. Thank you. Regards Varun ​ ___

Re: [gem5-users] Implementing tag-less cache architecture only for the last level cache

Hi Varun, You might want to check out http://learning.gem5.org/book/part2/. This walks you through how to create new objects in gem5 and culminates in a simple cache model (that you may be able to build off of). Additionally, you can check out the code in the gem5 source that was just committed (s

Re: [gem5-users] Implementing tag-less cache architecture only for the last level cache

​Hi Cho, Thank you for replying. The cache implementation is too huge and confusing when trying to understand its implementation. I didn't still understand it completely. Any specific pointers, or methods, to look at while I try to change the implementation??? Any idea which other files or classe

Re: [gem5-users] Implementing tag-less cache architecture only for the last level cache

Dear, Varun. In my opinion, you can make new class which inherit BaseCache or MemObject. As I think, if you implement tag-less cache in conventional cache class, you need to a flag which indicate tag-less cache and many conditional sentence everywhere operate differently with a conventional cache

[gem5-users] Implementing tag-less cache architecture only for the last level cache

Hi, I'm trying to implement a tag-less cache architecture only for the last level cache. As I understand, there is only one implementation for all levels of caches. How do I change only the implementation for the last level cache, leaving other caches being accessed in a conventional manner. Any
