Abstract
An extended data queue is added to the cache circuitry of a processor to handle extended data when the processor operates on a different architecture than the system it resides on. The extended data for each word coming into the processor is stored in the queue. If the extended data has some valid information, the word is replaced to ensure the information is not lost. If there is no valid information in the extended data, then the bits of the extended data are simply set to zero.
