This work describes SysteMorph, a feedback directed dynamic, online and adaptive hardware/instruction set architecture (JSA)/software co-optimization technology. The technology enables to optimize performance, power, and consumption energy for a system dynamically. We describe SysteMorphs elemental technologies those are an online profiling, a dynamic adaptive optimization and a smart hardware. Functionality morphing is one of the SysteMorph implementations for a system which consists of processor and reconfigurable logic. It reconfigures hardware dynamically then rewrites software to utilize the reconfigured hardware online. We demonstrated the SysteMorph on a reconfigurable processor by implementing functionality morphing. Online profiling, online synthesis, and binary rewriting are implemented and verified on the prototypal system. Then we propose a processor suitable implementing SysteMorph using a VUW execution unit.
