...It allows you to enter known starting vectors for a given code image for the micro. It will disassemble the code and follow through branches to assist in the separation of code and data.
Its included Fuzzy Function Analyzer companion uses a DNA Sequence Alignment Algorithm to locate similar code in multiple binaries to facilitate reverse-engineering and/or code recovery.
The original purpose of the Fuzzy Function Analyzer was to assist in code recovery where the source code for the current binaries got lost, yet the source code for an old binary was retained. ...
