An axiomatization of low-level parallelism in microarchitectures

This paper presents the heart of a universal syntax-directed proof system for the verification of horizontal computer architectures. The system is based on the axiomatic architecture description language AADL, which incorporates a comcise model of clocked microarchitectures. For a given description A of a host architecture, we show how to axiomatize A's microoperations and present powerful proof-rules dealing with the inherent low-level parallelism of horizontal architectures. They allow for a complete axiomatic treatment of the timing behaviour and dynamic conflicts of microprograms written in an A-dependent high-level microprogramming language based on S*.
