Method and apparatus for executing an instruction contingent upon a condition present in another data processor

摘要: A system for interfacing a Processor to Coprocessor using standard bus cycles. The processor, upon encountering in its instruction stream an having particular Operation word format, will transfer Command following the designated by Identity field word. Upon decoding word, respond with any of set response primitives which define functions requires perform support Coprocessor. interface provides all may require, including selective vectoring appropriate exception handlers.
