ABSTRACT:
A data storage system having a local processor and a plurality of memory storage elements is used for storing data from one or more external CPUs. The storage system includes a plurality of memory buffers, each coupled to a separate memory storage element. A data path control circuit is programmed by the local processor to control the transfer of data between the external CPUs and the memory buffers. Two interface circuits are coupled between the external CPUs and the memory buffers to provide two data paths for transferring data between the external CPUs and the memory buffers. The data path control circuit contains two independent sequencing circuits for selecting memory buffers. This allows one data path to be used for reading or writing to a number of the memory buffers while the other data path is simultaneously used for a different operation for the rest of the memory buffers.
