Abstract:
1. A method of generating a composite delta file on a computer server based on the differences between an original binary file and an upgraded binary file, the method comprising the steps of: segmenting the original binary file into a first plurality of segments of size N based on a memory map input file associated with the target device, wherein the size N of the first plurality of segments associated with the original binary file is determined by a sector size of a memory associated with the target device; segmenting the upgraded binary file into second plurality of segments of size N; detecting a first set of differences between a first segment from the original binary file and a first segment from the upgraded binary file; and generating a first delta file from the detected first set of differences, wherein the generating the first delta file using a greedy algorithm for generating delta files.
