On reliable software development for microprocessors

Microprocessor software is no longer microsized. It requires the same degree of methodology as is used for developing software for large mainframes. Software development for microprocessors involves much more than just writing the machine language instructions to perform some functions. This paper describes a systematic approach for microprocessor software development based on the concepts borrowed from large systems. The suggested methodology can go a long way to promise reliable software for microprocessor based systems. The approach lays emphasis on an ordered sequence of stages, well-supported development tools, good programming practices and management backing — all integrated into a systematic method. The methodology also suggests the use of an educational plan for new staff.
