This paper reviews the recent developments in microprocessors and digital IC’s with a special attention to applications to motion control area. First, the use of microprocessors and digital IC’s in the control of electrical motor drives is considered. General-purpose microprocessors and microcontrollers are then presented with emphasis on features that are necessary for the implementation of real-time control systems. High-pegormance advanced processors such as digital signal proces Tors (LISP’s), reduced-instruction-set computing (RISC) processors, and parallel processors are studied. Development and debugging tools required for developing sophisticated microprocessor-based control systems are considered. The capabilities of application-specific integrated circuits (ASIC’s) in motion control and their design process are examined. Typical application examples illustrating recent research works in digital motion control using microprocessors and digital IC’s are presented. The potentials of new devices are cmsidered for application to high-pegormanre drive systems. Trends for future development of the microprocessor technology for motion control applications are projected.
