Method for processing processor and processor system
First Claim
1. A processor processing method, suitable for a processor system, wherein the processor system comprises a CPU, a ROM coupled to the CPU, and a DSP having a memory unit for storing programs and a processor unit for processing data according to the programs, the method comprising the steps of:
- storing a plurality of programs and parameters required for processing the programs to the ROM;
downloading an initial program from the CPU to the memory unit of the DSP when a power is turned on;
transferring the programs and the parameters corresponding to each process request from the system processor external from the ROM to the memory unit of the DSP;
inputting data to be processed from the system processor external 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
outputting the processed data to the system processor external.

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.
