M.", editor= "McEwan, Alistair A. and Schneider, Steve and Ifill, Wilson and Welch, Peter H.", pages = "323--338", booktitle= "{C}ommunicating {P}rocess {A}rchitectures 2007", isbn= "978-1-58603-767-3", year= "2007", month= "jul", 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-p, 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 simplify design and implementation. This paper presents the USB (universal serial bus) device-driver infrastructure used in the RMoX system, demonstrating that a highly concurrent process-orientated approach to device-driver design and implementation is feasible, efficient and results in systems that are reliable, secure and scalable." } |
