STT-RAM Implementation about stonne HOT 2 CLOSED

Hi @meve01 ,

I think connecting the simulator to STT-RAM is feasible, but you will require to perform some changes.

I have another version of the simulator which will push soon, and it will include the connection with DRAMSimv3. However, if you want to incorporate your own connection with STT-RAM this is what you should do, depending on the scenario you want to model:

1. If you plan to implement an explicit decoupled memory hierarchy you will need to change quite a lot the module SDMemory. Here, you will have to separate these two modules into two: A first module will control the accesses to the DRAM and will feed the SRAM. Another one, will feed the multipliers based on the data in the SRAM. You could use a double buffer scheme. Eventtually, your model will connect with your non-volalite technology in DRAM. This scheme is quite complicated because it requires to synchronize both controllers to feed both the SRAM and the multipliers.
2. If your plan is to use an implicit memory hierarchy then it is easier. You will have to create your memory hierarchy model based on cache for example, having again your STT-RAM technology in the back-end. Here, the only thing you will have to do is to send the memory requests in SDMemory.cpp to the cache, and modify slightly the controller to manage the memory requests.

If you decide to go for it and need help, please let me know it. Also, do not hesitate to email me if you prefer so. This is my email: [email protected]

Thank you for your response @francisco-munoz!

I think our goal would be to use an implicit architecture that we'd make an STT-RAM.cpp and .h files for. This would use the second approach based on your response. I have the architectural model already done for STT-RAM but it exists in an NVSim simulator right now, so it will mainly be a matter of re-configuring that code to work with the STONNE simulator. My email is [email protected] and I will reach out to you soon if you're able to help me out at some point :).

Thanks again, Francisco!
