Abstract : An intelligent peripheral controller is described. The controller operates as a slave processor in a multiple processor environment. The system utilizes Motorola MC68000 microprocessors operating on VME bus and Eurocard construction. Each slave processor is totally self contained with individaul bus buffering, memory and input/output. Multiple slave processors connect to a common VME bus operating under the control of a master microprocessor. The master may operate under its own resident program or under the direct control of an external host computer. Passing of programs (algorithms) and exchange of data to this slave are controlled by the master until again interrupted. Each slave, although capable of independent operation, may operate as a synchronous or asynchronous system under hand shake control with the master or other slaves. The system was originally designed to control high speed (10,000 step/second) stepper motors to position a six degrees of freedom, hot wire anemometer probe.
