Generating difference files using module information of embedded software components
First Claim
1. A system for updating electronic files comprising at least one processor-based device hosting a module information extractor, the module information extractor:
- receiving byte streams including an original byte stream and a new byte stream, wherein each of the original and new byte streams include at least one module;
generating a new map file, new hex file, new binary file, and new device memory map (DMM) associated with the new byte stream;
reading module information of the modules of the new byte stream using information of the new map file and the new hex file;
comparing the new DMM with an original DMM using the module information, wherein the original DMM corresponds to the original byte stream;
identifying inserted and deleted modules of the new byte stream in response to the DMM comparison, the inserted modules being present in the new byte stream and absent from the original byte stream and the deleted modules being absent from the new byte stream and present in the original byte stream;
identifying remaining modules in which the contents remain the same as corresponding modules of the original byte stream, wherein the remaining modules are any modules of the new byte stream not identified as inserted modules; and
generating difference information representative of the inserted modules, deleted modules, and remaining modules in which the contents remain the same.

Abstract
In generating difference information between different file versions, a software component distributor (SCD) receives new files and corresponding original files. The SCD generates a new map file, hex file, and device memory map (DMM) for the new file. Module information is read from the new file using information of the new map file and hex file. The SCD, using the module information, compares the new DMM with the DMM of the original file, identifying inserted and deleted modules of the new file in response to the comparison. The SCD identifies remaining modules of the new file in which the contents remain the same as corresponding modules of the original file, where the remaining modules are modules of the new file not identified as inserted modules. The SCD generates difference information representative of the inserted modules, deleted modules, and remaining modules in which the contents remain the same.

13. A computer readable medium including executable instructions which, when executed in a processing system, performs differencing between electronic files, comprising:
-
receiving byte streams including an original byte stream and a new byte stream, wherein each of the original and new byte streams include at least one module; generating a new map file, new hex file, new binary file, and new device memory map (DMM) associated with the new byte stream; reading module information of the modules of the new byte stream using information of the new map file and the new hex file; comparing the new DMM with an original DMM using the module information, wherein the original DMM corresponds to the original byte stream; identifying inserted and deleted modules of the new byte stream in response to the DMM comparison, the inserted modules being present in the new byte stream and absent from the original byte stream and the deleted modules being absent from the new byte stream and present in the original byte stream; identifying remaining modules in which the contents remain the same as corresponding modules of the original byte stream, wherein the remaining modules are any modules of the new byte stream not identified as inserted modules; and generating difference information representative of the inserted modules, deleted modules, and remaining modules in which the contents remain the same.
