They are roughly speaking processors optimized for the task of transforming streams of data. SIMD in general purpose CPUs is an attempt to get a subset of DSP on the core . As an aside I might mention that it would make much more sense to put DSP functionality in the memory subsystem. A MIMD DSP on memory, mm :) MvH Dan Andersson >>The biggest reason to put an MP system there >>is that it is cheaper and uses less power than a single core solution with the >>same performance. > >Really?
