PROCESSOR HAVING MULTIPLE INSTRUCTION SOURCES AND EXECUTION MODES

摘要

A processor includes the standard mode of executing instructions from stored memory as well as a mode of executing from a separate instruction source. A programmable selector determines the source, and may be automatically programmed dependent on particular instructions. Streaming instructions from outside the processor provides an ability to have infinite program space. Further, booting processors in such an execution mode allows systems to be configured from external sources.
