Real-time executives for microprocessors

Abstract

Principles of real-time executives for microcomputer systems are discussed, together with some secondary functions. Salient features and limitations of three commercially available executives for 8080/5 and Z80 systems are described. An example is given illustrating the use of an executive in a multitasking application involving a simple data logger with a high priority data acquisition task, a low priority data converting task and storage task.
