Hi Christian, It seems a good start your implementation. I was quite lost but I think it can help me a lot. I am trying to make a useful implementation of this kind of memory and optimize their use allocating data using pseudo instructions, so be sure you will be notice if I am able to get it.

It can be found here [1] (scratchpad.cc, scratchpad.hh). It is nothing fancy and also work in progress. I just needed something to get me started, but maybe it helps you. Let me know when you get something useable. I would like to see a Scratchpad as a standard component.
