| Abstract(in English) | Effective power reduction is achieved through dynamic optimization of processor resources based on phase characteristics of programs. This work focuses on signature-based phase detection technique. Since existing work creates signatures from instruction blocks of fixed size, it may cause over-optimistic phase detections for applications whose the blocks that characterize phases are larger than the signature block. This work proposes the use of AND-signature and OR-signature, and realizes more efficient phase detection. We applied the method to dynamic reconfiguration of cache memory, and confirmed its effectiveness to power reduction. |
