Data processing system having scanner for searching memory for message having top priority and/or identity code identical with new message

摘要

A scanning unit is incorporated in a computer system communicable with another computer system for searching a random access memory unit for a message with the top priority as well as for identifying a received message with the message already stored in the random access memory unit, and a central processing unit is released from the scanning and the identification, thereby improving the throughput of given tasks.
