Multi-Grain Power Control Scheme in Ultra-Low-Power Data-Driven Chip multiprocessor: ULP-DDCMP
نویسندگان
چکیده
The authors are developing multi-grain power control scheme in ultra-low power data-driven chip multiprocessor (ULP-DDCMP) being suitable for a networking process in low power and a high performance. ULP-DDCMP consists of four ultra-low power CUEs (ULPCUE) and a token router distributing received packets to ULP-CUE by a round robin manner. ULP-CUE consists of an elastic self-timed pipeline (STP) having a flexibility that absorbs a sudden increase of a processing load. Because power consumption of the STP is proportional to processing load, the processing load can easily be assumed by observing power consumption. Moreover, the ULP-CUE has a supply voltage controller to adjust a performance of ULP-CUE to a demanded performance by observing the power consumption. In this paper, we propose a simulation method for developing multi-grain power control scheme in ULP-DDCMP.

This paper describes a runtime fine-grain power supply scheme based on the self-timed pipeline (STP) circuits. The STP works with its local hand-shake signal so that it does not require the global clock distribution, i.e., centralized control. Therefore, various power supply control for the STP can be naturally localized in both spatial and temporal domains without stopping its effective data t...
