Power Management Software optimizes chip energy consumption. (ThomasNet)
Designed for Xtensa configurable and Diamond Standard processors, Xenergy estimator with GUI allows software developers to evaluate trade-offs so their software can be optimized for power. Hardware designers can drive Xtensa processor configuration choices to lower total clock processor cycles required to perform given functional workload. Software developers can also use Xenergy to fine tune ...
