Hi Simon,
We already have a scratch pad memory for the compute GPU model (src/gpu-compute/). Take a look at the LDS code and how the Compute Unit code uses it. That should give you an idea how to implement a scratch pad for the CPUs. ________________________________ From: gem5-users <gem5-users-boun...@gem5.org> on behalf of Star_Duster <silver_ea...@sina.com> Sent: Saturday, February 11, 2017 5:04:48 AM To: gem5 users mailing list Subject: [gem5-users] How to simulate a ScratchPad Memory（SPM）in Gem5 Hello everyone, I am new to the Gem5, so I got some questions about how to simulate a SPM in gem5: 1.The reason why I want to simulate a ScratchPad Memory in gem5 is that I want to study some algorithm performance on the same data in the different position. My plan is replacing the L1 DCache/ICache with the SPM ( as on-chip memory ), so I can put the data in different place (on the SPM) as I wish. Also I need to output the trace of the memory access ( the SPM) to statistical analysis. I don't know if my plan is all right, or you have some better idea？ 2. If my plan works, what exactly should I do to realize it ( may be need some specific steps)? how can I place the data and tell the system (Gem5) where it is? And how can I output the trace？ Thanks again for any of your help, and looking forward to your reply. Best wishes, Simon
