摘要： A digital signal processor for determining the maximum and minimum values of a plurality of data items wherein operations of an arithmetic logic unit and data memories are controlled by micro-instructions, including a device for decoding specified bits of an operand of the micro-instruction, a device for detecting a value of a condition code which has been designated by an output of the decoding device, and a control device for executing a logical operation between the output of the detection device, which becomes "1" if the value of the condition code is true, and a decoded value of an operation code of the micro-instruction and to generate a control signal for the arithmetic logic unit on the basis of a result of the logical operation.
