Abstract

The application of dual-port-memory-based dual- and triple-microprocessor systems for improving the speed of transducer output signal processing which involves corrections, using interpolating polynomials, for input-output nonlinearities and effects of disturbing variables is presented. In the architecture of the triple-microprocessor system, a new concept of blackboard memory segments for passing a large amount of common data among the microprocessors is introduced. Significant processing-speed improvement over single-microprocessor implementation is shown by analytical evaluation
