A modular system comprising a microprocessor having a system bus (control address and data) and one or more programmed logic arrays connected to said system bus. Three system configurations are shown by way of example, Macroprocessor, Peripheral Input/Output and Direct Memory Access applications. The microprocessor executes a standard set of instructions and addresses each programmed logic array. Each array executes a specific instruction, beyond the standard set of instructions, upon receipt of its address.
