ABSTRACT:
A microprocessor is provided which supports a start of access instruction. Upon execution of the start of access instruction, the microprocessor establishes a local access mode provided by the instruction. Memory operands fetched for instructions subsequent to the start of access instruction (in program order) are fetched in accordance with the local access mode. Memory operands fetched for instructions prior to the start of access instruction are fetched in accordance with a global access mode established for each page of memory.
