This paper introduces a set of design principles that aim to make processor architectures amenable to static timing analysis. Based on these principles, we give a design of a hard real-time processor with predictable timing, which is simultaneously capable of reaching respectable performance levels. The design principles we identify are recoverability from information loss in the analysis, minimal variation of the instruction timing, non-interference between processor components, deterministic processor behavior, and comprehensive documentation. The principles are based on our experience and that of other researchers in building timing analysis tools for existing processors.
