NEW COMPUTER ARCHITECTURES.

Abstract

RISC (Reduced Instruction Set Computer) and parallel processing are two aspects of computer architecture that have received a great deal of academic interest over the past five years or so. Both are also being tested in commercial systems. Both concepts suffer from lack of precise definitions and widely-accepted terminology. While RISC deals mainly with CPU and compiler design, parallel processing relates mainly to system architecture and operating system structure. The aim of RISC is to maximize the performance available from a single CPU; parallel processing achieves performance gains by employing multiple processors.
