The SAGE operating system

Abstract

The author describes SAGE, an operating system designed for real-time supervisory control applications. The SAGE kernel runs on a Motorola 68020 processor board and provides a variety of services, including process and memory management, protocol support, and precise timing facilities. In addition, file system capabilities are provided through remote procedure calls made over a LAN interface. Development tools, which run on a Sun workstation, allow programs to be compiled and dynamically downloaded to the SAGE host as needed.<>
