A Real-Time Process Scheduler for a Ring-Type Microcomputer Network

This paper describes the design of a real-time process control scheduler for microcomputers in a distributed process control scheme with a ring-type network configuration. For simplicity, static priority based round-robin scheduling policy is used where working time-slice, for different processes can be variable. The memory size for the process scheduler modules is estimated at about 2.5 Kbytes using an Intel 8085 instruction set and a RAM requirement of about 1 Kbyte.
