I f the address bus contains n electrical lines, the processor can uniquely ad dress up to 2^n such locations. n 2^n application software Describes software modules specific to a particular embedded project. Theapplication software is unlikely to be reusable across embedded platforms, simplybecause each embedded system has a different application. assembler A software development tool that translates human-readable assembly languageprograms into machine-language instructions that the processor can understandand execute.
