Data feeder control system for performing data integrity check while transferring predetermined number of blocks with variable bytes through a selected one of many channels

摘要

Multiple numbers of "sets" of sender-receiver units operate concurrently to transfer blocks of data. The number of blocks to be transferred in each set is predetermined by a main host computer which registers the number-of-blocks-to-be-transferred into a protocol- controller in each set of sender-receiver units. An associated data feeder control system monitors the number of data blocks residing in a buffer memory, which has dedicated storage for each sender-receiver unit, and will only permit data block transfer to receiver units only to the amount presently available in the buffer memory until, eventually, the predetermined number of data blocks, for each set, is transferred to completion.
