A Process Oriented Approach to USB Driver Development

Abstract. Operating-systems are the core software component of many modern computer systems, ranging from small specialised embedded systems through to large distributed operating-systems. The demands placed upon these systems are increasingly complex, in particular the need to handle concurrency: to exploit increasingly parallel (multi-core) hardware; support increasing numbers of user and system processes; and to take advantage of increasingly distributed and decentralised systems. The languages and designs that existing operating-systems employ provide little support for concurrency, leading to unmanageable programming complexities and ultimately errors in the resulting systems; hard to detect, hard to remove, and almost impossible to prove correct. Implemented in occam-π, a CSP derived language that provides guarantees of freedom from race-hazards and aliasing error, the RMoX operating-system represents a novel approach to operating-systems, utilising concurrency at all levels to ...
