Abstract
The pin count of a processor is substantially reduced while effectively maintaining processor performance by using a staging register to receive and store a first data segment from a bus. A second data segment is received from the bus in a subsequent bus cycle and loaded into a cache. A steering circuit dynamically selects the transfer of the first or the second segment to a processor core, and orders positioning of the first and second data segments into the cache. In some embodiments, the cache is a first level cache and a second level cache is inserted between the bus and the processor. In these embodiments, the processor includes a bypassing circuit for designating the ordering of bus data in response to a memory access that misses the first level cache and hits the second level cache.
