ABSTRACT:
A disclosed coprocessor receives a user-defined command during execution of an instruction including the user-defined command, and performs a predetermined function in response to the user-defined command. The user-defined command includes multiple ordered bits having values assigned by a user. In one embodiment, the coprocessor includes logic coupled to receive the user-defined command and a datapath. The logic produces a control value in response to the user-defined command. The datapath receives data and the control value, and performs the predetermined function dependent upon the control value. In one embodiment, the predetermined function is a motion estimation function. Data processing systems are described including a processor coupled to the coprocessor. Another disclosed data processing system includes an arbiter coupled between a processor and multiple coprocessors. The arbiter receives the user-defined command, and provides the user-defined command to one of the coprocessors dependent upon the user-defined command.
