ABSTRACT:
In an I/O pulse processing apparatus associated with a microcomputer, an I/O processing task is required by the microcomputer in the form of the combination of task microinstructions, each of which includes an instruction code specifying one of basic I/O processing operations and a code for specifying one or two registers necessary for executing the basic I/O processing operation. The apparatus includes an I/O task register part having a task register group consisting of plural task registers, which store the task microinstructions supplied from the microcomputer and necessary for executing the task required thereby, and a task signal generator for producing address signals for the task register group, according to which the task microinstructions are read out successively from the task register group. There is further provided an I/O operation part including a register group comprising plural registers, each of which is capable of being specified by a task microinstruction and performing a register function necessary for completion of the basic I/O processing operation specified by the instruction code of the task microinstruction, and an arithmetic unit connected to the register group to perform an arithmetic operation on the basis of data from the specified registers in accordance with control signals produced by decoding the task microinstruction.
