ABSTRACT:
An input/output system includes a local memory module including a cache store and a backing store. The system includes a plurality of command modules and a system interface unit having a plurality of ports, each connected to a different one of the command modules and to the local memory module. The cache store provides fast access to blocks of information previously fetched from the backing store in response to memory commands generated by any one of a plurality of command modules during both data transfer and data processing operations. The local memory module includes apparatus operative in response to each memory command to enable the command module to write into cache store the data which is requested to be written into backing store when it is established that such data has been previously stored in cache store.
