Yuzhao Tian, Yunhui Wang, Li Zhou, Yi Feng · 2022
With the continuous progress of IC technology, DSP has been widely used in the product application of various digital signal processing algorithms. For some special applications, in order to avoid the disassembly of products, a high-reliability on-line update method for DSP software is implemented. This paper brings a design procedure and software implementation, describing the DSP software upgrade, loading and the self-repair process. With the purpose of avoid the risk of program jump and software upgrade failure caused by abnormal operation, then the reliability and security of DSP software online upgrade will be improved.
