Abstract

Typical 32.bit microprocessors include the capability to detect illegal opcode combinations and force an exception to be taken if an attempt is made to execute an illegal instruction. In addition, service requests by external coprocessors presented to the main processor in the form of a coprocessor primitive are checked to determine the validity of the primitive encoding.
