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

Abstract

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.

AI Technical Summary

Benefits of technology

This technology allows for easy access to programs that have been developed through computer simulations or hardware description techniques without having complex coding processes involved. It also includes an improved version called Watch Dog Circuit (WC), where it can store more complicated instructions during simulation runs than traditional methods like Programming Linescope Code (PLCG) memory systems. Additionally, this new system simplifies the procedure used when writing code from scratches onto disks instead relying solely upon random addresses provided within certain fields inside the CPU's registers. Overall, these technical improvements make programming and playback tasks easier compared to older ways such as PCIE cards.

Problems solved by technology

This patented describes how certain functions are performed when programs require periodic input from their CPU (Central Processor) or other components during execution. These processes involve generating regular dogs called feeds, allowing them to access memory quickly without complex calculations. However, these techniques have limitations such as requiring specific hardware devices like timers or counters, making writing new instructions difficult if they don't happen right beforehand. Additionally, some methods may result in errors due to incorrect timing caused by factors like temperature changes or power supply variations.
