Long ago coprocessors were pretty common but nowadays chip companies don't use it anymore. Although this might change soon as AMD is considering to develop a co-processor with Clearspeed to soup up AMD's multi-core x86 processors.
“Clearspeed is talking to AMD about producing a closely coupled co-processor,” said Jeff Underhill, business development manager for 64-bit embedded applications at AMD.
Behind the talks are worries that it is not achieving sufficient performance out of its multi-core processors. Stoking those concerns was the stunning performance of the Sony/Toshiba/IBM microprocessor Cell.
“Cell was a wake up call. Absolutely, things are under way at AMD as a result in looking at future products,” said Underhill.
