DEVICE AND METHOD FOR DEBUGGING DSP BY USING DSP FOR DEBUG

摘要

PURPOSE: A method and a device for debugging DSP(Digital Signal Processor) by using DSP for debug are provided to get the data like information about the state of DSP when a problem of a digital signal handling device occurs through a zig system. CONSTITUTION: A DSP(Digital Signal Processor) debugging device by using DSP for debug consists of a digital signal handling device and a zig system. The digital signal handling device, which stores the data that are input to the digital signal handling device from a certain point of time to now by operating the object program for debug, and the inner memory state. The zig system initializes the state of memory by reading the state value of the memory from the digital signal handling device, and finds the cause of the problem by operating the program repeatedly.
