Abstract
A data processing system having a bus master, a cache, and a memory which is capable of transferring operands in bursts in response to a burst request signal provided by the bus master. The bus master will provide the burst request signal to the memory in order to fill a line in the cache only if there are no valid entries in that cache line. If a requested operand spans two cache lines, the bus master will defer the burst request signal until the end of the transfer of that operand, so that only the second cache line will be burst filled.
