Abstract

PURPOSE: To make it easy to extend and modify the functions of processing by bringing execution to effect by assigning a subunit with the data processing function by a microprogram.
CONSTITUTION: Microprogram control part MC1 outputs arithmetic data, the unit address of a subunit and its control signal 9 to C bus 20. Respective subunits SU1... SUn decode the unit address and the assigned unit fetches the information from the bus and performs processing. Control over the operation in the subunit is exercised, on the basis of the control signal from MC1, by decoding the information by the subunit. To extend or change the processing functions, an additional subunit is connected to the bus and the microprogram is only modified.
