Program burning and backward-reading method with watchdog circuit and based on DSP chip

The invention discloses a program burning and backward-reading method with a watchdog circuit and based on a DSP chip. Hardware is connected with a micro processor by means of an upper computer through a simulator, and peripheral circuits of a DSP comprise the watchdog circuit and an ROM circuit. The method is characterized in that burning and backward-reading processes of a target code are achieved, the burning program and the backward-reading program both have a dog feeding function, the situation that a burning process is interrupted due to resetting of a dog feeding circuit cannot occur, reliability is high, CCS software is made full use of to achieve the transmission function of data between the upper computer and the micro processor, file operations are not needed in the whole process, only the CCS software needs to be operated in the burning and backward-reading processes and operations are easy.
