In the paper,a scheme to improve the HDiffPatch algorithm and realize the differential upgrade of small memory on the Fudan microcontroller is proposed,that is,the Flash space in the microcontroller is used to replace the RAM space occupied by the algorithm,so as to reduce the requirement of the algorithm for the RAM space of the microcontroller,and to meet the differential upgrade of small memory microprocessors.At the same time,the algorithm memory allocation release function is optimized to maximize the use of RAM space.Finally,the experiment results show that the improved HDiffPatch algorithm can achieve differential upgrade on small memory embedded devices.
