Abstract
This paper gives an overview of the real-time specification of a commercial RISC processor. The specification is at two related levels, with an abstraction relation defined between them. The lower level specification models separate stages of execution of up to five overlapped instructions. The higher level specification abstracts from the lower level to recapture an atomic, instruction level view of code execution. The load word instruction is used as an example to illustrate the specification at both levels.
