Design and Implementation of an Operating System for the IBM Personal Computer

摘要

This thesis documents the design and implementation of an operating system, designated PCOS, developed in order to provide a pedagogical aid which could be used to provide students with a better understanding of operating system principles. PCOS (Personal Computer Operating System) is intended to be a simple yet functional operating system which students can analyze, modify, and extend. PCOS was designed and implemented on an IBM Personal Computer. However, the strategy used to structure PCOS along with the algorithms used to implement PCOS are applicable to most contemporary computer systems. This thesis presents the requirements and design criteria which were used to guide the design of PCOS. The decisions made during the design of PCOS are discussed. The algorithms and data structures used to implement PCOS are discussed. And, further development of PCOS is also discussed. (Author)
