ABSTRACT:
An Input-Output Interface Data-Transfer Control Unit, designated as a Line Control Processor, which provides the execution of instructions in accomplish data transfers between a main data processing system and a plurality of different types of peripheral devices. Further, said Line Control Processor provides for the buffering of at least two complete blocks of message data, thus to prevent access errors, since complete record length message transfers can occur in any given data-transfer cycle. The Line Control Processor operates with a standard communications and control discipline which makes the eccentricites of various types of peripheral units transparent to the main system. The Line Control Processor executes data-transfer instructions within the overall system thus relieving the central processor of an involvement in these tasks. Each Line Control Processor handles data-transfer operations with a specific peripheral device and the main system, and also provides "status-count" numbers which provide the main system with information for logically determining the next processing step to accomplish.
