ABSTRACT:
A data processing system has a bus meter, a memory capable of transferring operands requested by the bus master, and a cache for temporarily storing a selected number of the most recently transferred operands. If the memory provides an operand or a portion thereof which is insufficient in size or alignment to fill a complete entry in a line in the cache, the bus master automatically transfers additional operands adjacent in the memory to the requested operand sufficient to fill that entry.
