On data prefetching in flexus

[Mahmood Naderan]

Hi,
1- In the nCache namespace, there are some stat counter (I found
prefetchReads and misses_user_D_PrefetchRead) which have never
incremented. Should I consider that as a not implemented code? Or
something else.

2- I didn't find any data prefetching function in the source code.
Next line prefetcher is implemented for instruction. Did I understand
correctly?

3- what does sys-ufetch-Prefetches stand for? If it shows the number
of instructions prefetched then the following counters are odd:
   sys-cycles                               224000000
   sys-uarch-Commits                        197481675
   sys-ufetch-FetchAccess                   133034670
   sys-ufetch-Prefetches                    688565

Thanks for any suggestion.
