Abstract: The present invention provides a method and apparatus for saving and restoring soft repair information. One embodiment of the method includes storing soft repair information for one or more cache arrays implemented in a processor core in a memory element outside of the processor core in response to determining that a voltage supply to the processor core is to be disconnected.

Abstract: A system is disclosed for improving the efficiency of data transactions to a non-cacheable address, or to a block-accessed device. A stream read buffer and associated logic is used to temporarily store the non-cacheable data, or to store large blocks of data from a block-accessed device. The stream read buffer loads the data upon the occurrence of certain predefined events, as determined by the associated state logic. Similarly, the stream read buffer flushes its contents when the stored data is not being accessed, or after the expiration of a particular time frame.
