A vector execution unit for use in a digital signal processor enables a new set of instructions. The unit comprises a first input port for receiving at least a first input data vector, an instruction decoder, a vector output port, and least one data-path. The instruction decoding unit is arranged to control the data-path to perform a comparison related to the first input data vector, and the processor comprises an integer port arranged to output the result of the comparison in the form of a decision vector to a memory unit or a functional unit in the digital signal processor. Alternatively or in addition, the integer port is also arranged to receive a decision vector of integer data, and the instruction decoding unit is arranged to control the data-path to process the first input data in dependence of the value of the integer data. |
