I think I asked a question but now see it has been deleted!!
The question was about the hardware prefetcher for Epiphany processor. Where can I find documentation about that? How can I program and change its configuration?

Well there are different hw prefetcher. Either for instruction or data cache.
There are different methods also such as next line or stream prefetcher.
These method are in commercial product such as intel or amd or ibm power.
I saw a presentation by Andreas that had a table which shows why he decided to incle or not include somethind in the Epiphany.... For example he saud that he did not include the branch target buffer in Epiphany

The Epiphany architecture does not have caches.
Consequently, there are no cache prefetchers.

Looking at the datasheet [1], what is the "32+ distributed memory" per core?
