Hi Ciro, Thanks for your reply! I don't remember seeing this patch before. I will check it out.
The reason I specified RUBY is that one solution I found posted used a cache as a second level TLB and modified the port connections accordingly. However, that was a cache from the classical system and therefore wouldn't work with RUBY. Thanks again!
