Abstract

In order to apply formal verification methods to actual microprocessors, we study the functional semantics of microprocessors of the "Von Neumann Machine" type, at different specification and description levels.We settle a functional formalism from which the semantic equivalence between adjacent levels will be proved.Here, we propose a general methodology to define the functional semantics of a processor at the Microprogram level. We also present the correspondence between this level and the Machine Instruction level.
