AI Technical Summary

Technical Problem

Existing devices with limited memory capacity face challenges in updating software due to insufficient free space in both non-volatile and working memory, preventing successful download and execution of update software.

Method used

The update assistance device divides update software into multiple blocks, each smaller than the available free capacity of the working memory, and supplies these blocks to the memory in a controlled manner, ensuring partial updates can be completed even with limited memory resources.

Benefits of technology

This approach allows successful partial updates of software in devices with limited memory by managing block sizes based on available space, ensuring efficient software updates without overwhelming the memory capacity.
