More Information
Summary:The invention discloses a digital signal processor and a digital signal processing method. The digital signal processor is used for determining an extremum among a series of values. The digital signal processor comprises a register used for storing the series of values, an accumulator used for storing the extremun among the values, and a comparator for continuously receiving the series of values from the storage and executing a continuous cycle search instruction to compare a current value with the vale stored in the accumulator and store the extremum after comparison in the accumulator. The digital signal processor and the digital signal processing method can more effectively execute the instruction and have relatively low delay and power consumption.
