ABSTRACT:
An embodiment of the invention is a processor for providing simultaneous access to the same data for a plurality of requests. The processor includes cache storage having an address sliced directory lookup structure. A same doubleword detection unit receives a first instruction including a plurality of first instruction fields on a first pipe and a second instruction including a plurality of second instruction fields on a second pipe. The same doubleword detection unit generates a same doubleword signal in response to the first instruction fields and the second instruction fields. The cache storage reads data from a single doubleword in the cache storage and simultaneously provides the doubleword to the first pipe and the second pipe in response to the same doubleword signal.
