Abstract
A processor processing method suitable for a processor system. The processor system comprises a CPU 10, a ROM 20 coupled to the CPU, and a DSP 30 having a memory unit 50 for storing programs and a processor unit 40 for processing data according to the programs. The ROM stores a plurality of programs and parameters required for processing the programs to the ROM. The CPU downloads an initial program to the memory unit of the DSP when a power is turned on. Then, the programs and the parameters corresponding to each process request from the system processor external are transferred from the ROM to the memory unit of the DSP. The data to be processed is input from the external of the processor system to the DSP; processing the data by the processor unit based on the programs and the parameters that are transferred to the memory unit, and then the processed data is output to the system processor external.
