Abstract

A multimicroprocessor system, based on Intel 8085 processors, has been designed and applied in digital signal processing. Multiple master/dual bus multiprocessor architecture has been applied, which enables up to eight masters to run concurrently. Several inter-master communications, as communication through common memory, synchronization and mutual exclusion, have been used. One master of the system, dedicated to digital signal analysis, has been realized as real-time multitasking system, using the RMX/80 operating system. The major steps in designing this system are described in the paper. They include designing the hardware and the software components of the system, designing and coding user tasks and generating the software configuration. Intertask communication, based on the Command task, has been proposed. It provides flexible software communication between this master, realized as the multitasking system, and the other part of the multimicroprocessor system. The specific functions of digital signal analysis have also been described.
