Abstract
A system for interrupting loading of data into a high speed memory device from main storage when a processor requests cache access. A high speed cache is connected to main storage for storing at least a subset of the data residing therein, and the cache can be directly accessed by a processor. In a preferred embodiment, a buffering device is connected to main storage and to the cache for buffering data to be loaded therein. The data buffer is adapted to receive data from main storage continuously and is adapted to transfer the data to the cache continuously unless the cache is being accessed by the processor.
