DIGITAL SIGNAL PROCESSING METHOD AND DIGITAL SIGNAL PROCESSING SYSTEM

摘要

PPROBLEM TO BE SOLVED: To improve the quality of an output signal and to reduce electric power consumption by effectively utilizing the capabilities of a processing system which performs a plurality of arithmetic processing in parallel or in time sharing even in case of the occurrence of a processing remainder. PSOLUTION: The digital signal processing device is equipped with an arithmetic processing result storage memory M1 which stores the result of the arithmetic processing of the first arithmetic processing means 11 and the second arithmetic processing means 12, an arithmetic processing information storage memory M2 which stores the arithmetic processing control information on the arithmetic processing of each of the respective arithmetic processing means, a processing quantity monitor means 13 which monitors the processing quantity of the first arithmetic processing means, and a processing content determination means 14 which determines the processing contents of the second arithmetic processing means 12 using the processing quantity and the arithmetic processing control information, in which the capabilities of the processor are dynamically allocated with respect to the increase and decrease of the processing quantity.
