The design of a real‐time operating system for a minicomputers. Part 1
W. F. C. Purser, D. M. Jennings · Software Practice and Experience · 1975
Abstract The design objectives of real‐time operating systems for minicomputers are considered. Simplicity, efficency and avoidance of superfluities are the main criteria. A typical multitasking structure is sketched and the executive elements to support it are analysed. Examples of their use in simple Input/Output are given. Filing systems are then discussed, followed by the interface with the operator. Finally, the problem of linking and loading the modules which make up a simple core‐resident real‐time system is reviewed.
