Abstract

PURPOSE: To establish the channel unit of common control system of high performance, by giving the function to process in good order for the advanced control request to a plurality of items to the control system processing a plurality of items.
CONSTITUTION: The system is provided with the microprogram control section 11 performing the starting to the program of a plurality of channels, command end processing and command chain processing, and executing the interrupt processing to CPU, data transfer control section 12 controlling the data buffer of a plurality of channels and executing data, and the data transfer control section 13 performing the control of data transfer between the channel to a plurality of channels and the main memory unit, and executing the data chain control and the indirect data control. Further, the advancing of data and the channel command word chained is made at the control section 12, and the address indirectly designated is converted with the control section to the data address actually performing data transfer, and the order of processing is designated with the control section 12 when a plurality of requests are present in one channel.
