  • Handling of coprocessor instructions in a data processing apparatus
    Patent number: 6883085
    Abstract: The present invention provides a data processing apparatus and method for handling of coprocessor instructions. The apparatus comprises a processor core for processing a sequence of data processing instructions, and a plurality of coprocessors for executing coprocessor instructions provided within the sequence of data processing instructions. Each coprocessor instruction has a virtual coprocessor number associated therewith for use in identifying which of the plurality of coprocessors is to execute that coprocessor instruction. For each coprocessor instruction with its associated virtual coprocessor number, there are multiple coprocessors within the plurality that may execute that coprocessor instruction, and a coprocessor determination logic is provided to determine for each virtual coprocessor number, based on a mapping, which coprocessor is assigned that virtual coprocessor number, and hence will execute instructions associated with that virtual coprocessor number.
