Reusable common module software for embedded systems

Hardware and software for a mission processor (MP) consisting of several types of 1750A-based modules have been developed. Extensive communications and built-in-test (BIT) software were developed for each of the 1750A-based modules taking advantage of the commonality between modules. Approximately 65% of the module startup and BIT software was common between modules. The common software library implemented on the MP resulted in several advantages which include common interfaces, reduced software development effort, reduced code size, fewer units to test, and faster software development. The software and the methodology used to develop it are discussed in detail
