Following a brief outline of the background of the MUS project, the aims and ideas for MU5 are discussed. A description is then given of the instruction set, which includes a number of features conducive to the production of efficient compiled code from high-level language source programs. The design of the processor is then traced from the initial ideas for an associatively addressed "name store" to the final multistage pipeline structure involving a prediction mechanism for instruction prefetching and a function queue for array element accessing. An overall view of the complete IVIU5 complex is presented together with a brief indication of its performance.

Portability of MUSS compilers is achieved by using an abstract machine model concept. Two different abstract models, both suited for multi‐language multi‐machine usage, have been developed and evaluated. These models differ mainly in the level of interface to the compiler. The form of these models and the performance of two compilers, each using both models, are presented.
