Abstract:

The design, analysis and performance evaluation of the architecture of a mutiprocessor is presented. The architecture is a hierarchically structured, functionally distributed, multiple microcomputer system. Its operating system is a multi-level structure implemented in an optimal combination of hardware, firmware, and software. This architecture is suited to any application, such as process control or real-time system simulation, in which the basic computational tasks do not change in time. Control functions are distributed among the microcomputer however, the scheduling and execution of these tasks is governed at each microcomputer level by a local, real-time operating system. This local operating system is implemented primarily in firmware to minimize overhead. However, the control structure is designed to be independent of implementation so that a variety of microcomputers can be utilized together. Moreover, it is possible to add to each local processor an additional subprocessor which implements the operating system.
