Embedded Processor Based Real time System is not only a growing need of the commercial industry but will also be required for all active weapons, avionics, telecom, industrial control, aerospace and consumer electronics. Although processor based systems are available but it is difficult to change its firmware at modular level with respect to the specific application. Keeping in view this limitation, author has designed a high performance, general purpose, cost minimized and stand alone Real Time System using Intel Embedded Processor 80C186.
