A design system for a special purpose processor executing algorithms described by high level language is discussed. The system can generate an optimized architecture for the processor and also supply a specialized high level language compiler for the processor. A new optimization procedure is introduced to find effective functional blocks that can contribute to the improvement of performance. Functional blocks are found by simulation of the frequently appearing patterns of execution in the algorithm and used to yield a useful combined instruction.
