A means and method to receive and store a continuous flow of data items
being processed in a data processing system in which data items are
received from multiple sources simultaneously. The invention provided for
simultaneous retrieval of previously stored data from multiple
destinations while providing low latency of the retrieved data. The
invention utilizes multi-port random access memory or register arrays with
fewer ports than the number of actual data sources or data destinations
within the system. The disclosure teaches a means of providing the control
of data flow to multi-port simultaneous access memory systems, utilizing
the control paths in the memory control systems rather than the data paths
in such systems. The system eliminates or reduces the need for memory
buffers to manage data flow into or out of system memory devices which
have a limited number of ports or paths connecting system memory to the
input and output systems of the data processing system.
