a system generation for a small operating system
A system generation utility has been developed to assist students in producing IBM PC-based multitasking applications targeted for the small operating system (SOS) developed by Jerry E. Sayers. Our aim is to augment SOS by enabling a student to interactively tailor the characteristics of the operating system to meet the requirements of a particular application. The system allows the user to adjust factors such as: initial state, priority, and scheduling method of concurrently executed tasks, and, also, use of system resources. A custom operating system is produced by invoking a MAKE utility to bind SOS with application-specific code, in addition to intermediate source code created during the system generation process.Testing of the system included implementing an application that adds column vectors in a 5  5000 matrix concurrently. Further testing involves using the system generation utility along with SOS as part of an undergraduate operating systems class at East Tennessee State University.
