Foil 40 Comments on Special Purpose Devices

From New CPS615Master Foils-- 26 August 96 Basic Simulation Track for Computational Science CPS615 -- Fall Semester 96. by Geoffrey C. Fox


One example is an Associative memory - SIMD or MIMD or content addressable memories
This is an an example of a special purpose "signal" processing machine which can in fact be built from "conventional" SIMD or "MIMD" architectures
This type of machine is not so popular as most applications are not dominated by computations for which good special purpose devices can be designed
If only 10% of a problem is say "track-finding" or some special purpose processing, then who cares if you reduce that 10% by a factor of 100
  • You have only sped up the system by a factor 1.1 not by 100!
