because the complexity of embedded computer-controlled structures raises, the current commercial perform for his or her improvement offers reason for hindrance, specifically for safety-critical functions the place human lives are at stake. using software program in such platforms has elevated greatly within the final decade. Formal tools, in keeping with enterprise mathematical foundations, offer one potential to aid with lowering the chance of introducing mistakes in the course of specification and improvement. there's at the moment a lot curiosity in either educational and commercial circles in regards to the concerns concerned, however the options nonetheless desire additional research and promulgation to make their frequent use a reality.

This ebook offers result of study into thoughts to assist the formal verification of combined hardware/software structures. points of process specification and verification from requisites right down to the underlying are addressed, with specific regard to real-time concerns. The paintings provided is basically dependent round the Occam programming language and Transputer microprocessor paradigm. The HOL theorem prover, in line with larger order good judgment, has mostly been utilized in the applying of machine-checked proofs.

The publication describes examine paintings undertaken at the collaborative united kingdom DTI/SERC-funded info Engineering Dictorate Safemos venture. The companions have been Inmos Ltd., Cambridge SRI, the Oxford college Computing Laboratory and the college of Cambridge machine Laboratory, who investigated the issues of officially verifying embedded platforms. crucial result of the venture are awarded within the type of a sequence of interrelated chapters via undertaking participants and linked body of workers. moreover, overviews of 2 different ventures with related pursuits are integrated as appendices.

The fabric during this ebook is meant for computing technology researchers and complex business practitioners attracted to the applying of formal how to real-time safety-critical structures in any respect degrees of abstraction from requisites to undefined. furthermore, fabric of a extra common nature is gifted, that could be of curiosity to managers answerable for initiatives utilising formal equipment, in particular for safety-critical-systems, and others who're contemplating their use.
