A self-optimizing embedded microprocessor using a loop table for low power

We describe an approach for a microprocessor to tune itself to its fixed application to reduce power in an embedded system. We define a basic architecture and methodology supporting a microprocessor self-optimizing mode. We also introduce a loop table as a tunable component, although self-optimization can be done for other tunable components too. We highlight experimental results illustrating good power reductions with no performance penalty
