Abstract
PURPOSE: To obtain the unit small and low in cost, by providing the microprogram controller independently of the channel controller CHC controlling a plurality of channel units CH, and the channel unit CH controlling the input and output units.
CONSTITUTION: CHC1 memorizes the microprogram μPRG, and consists of the μPRG control section 3 executing with sequential readout, CPU interface control section 4, main memory unit MEM interface control section 3, CH interface control section 6 and the control section 7 for the buffer memory and CHC internal part, and it executes the data transfer operation between MEM and the input and output unit according to the input and output instruction from CPU. CH2 is constituted with the μPRG control section 8, CHC interface register group 9,I/O interface latch group 10, and CH internal control register group 11, controlling a plurality of input and output controller. Accordingly, μPRG can respond to required functions, then small size and economical unit can be made.
