Abstract

Until now, the design of operating systems assumed the kernel as an extension of a single processor's physical layer supporting user processes in the one cpu. The present multiprocessor operating systems duplicate this set-up in multiple cpus in order to reduce complex inter-processor communication. Since the functions of a kernel in both a uniprocessor and a multiprocessor operating system have a tendency to grow in an unlimited manner, the redesign of both an intelligent and high speed kernel, becomes an important issue. In this paper, I describe firstly, a brief summary of the current status of a kernel, and secondly the future requirements of a complex operating system. Finally, I present part of a possible solution to construct a high speed kernel based on multiple processors.
