Abstract

PURPOSE: To reduce the control memory capacity of an input-output controller by storing a microprogram with all function in a common memory.
CONSTITUTION: An input-output subsystem, consisting of several input-output controllers 4 and several input-output units 2, is equipped with common memory unit 5. Each input-output controller 4 reads a needed microprogram routine from common memory 5 at need and then stores it in execution memory 10, so that input- output control operation will be carried out on the basis of the stored microprogram routine.
