A METHOD AND APPARATUS FOR COORDINATING EXCEUTION OF AN INSTRUCTION BY A PROCESSOR

摘要

The processor will transfer a command word following the operation word to a particular coprocessor designated by a coprocessor identity field in the operation word. Upon decoding the command word, the coprocessor will respond with any of a set of response primitives which define functions which the coprocessor requires to processor to perform in support of the command by the coprocessor. The interface provides for all functions which the coprocessor may require including selective vectoring to apparopriate exception handlers.
