Abstract
A data processing technique with which a CPU core accesses memory devices over a bus. Some of the memory devices are on-chip, and some may be off-chip. In order to optimize its operation, the CPU core accesses the on-chip devices via a core buffer interface unit ('BIU') which has been tuned to on-chip operation. Off-chip devices communicate with the CPU core via a system BIU which translates the on-chip bus transactions to meet the off-chip device requirements.
