ABSTRACT:
Streaming buffer renaming for memory accesses issued by a microprocessor to an external memory via a system bus allows up to N fetch accesses at any one time for M physical streaming buffer locations, where N is greater than M. When a fetch within the processor misses the instruction cache, the fetch address is placed in the streaming buffer. When the data has been fetched from the external memory, it is returned to the streaming buffer and placed into one of the M physical buffer locations. The data within the streaming buffer is returned to the instruction cache of the processor only if it is to be used in accordance with the computer program being executed.
