Abstract
Modern microprocessors requires dependability as well as high-performance and powerefficiency. We are investigating multiple clustered-core processors to achieve three requirements. The proposed processor executes the program with considering the trade-off between performance, power, and dependability. When high performance is requested, the whole processor is utilized. In contrast, when low power is expected, the portion of the processor is utilized. The unused portion is turned off and thus power consumption is reduced. Furthermore, when high dependability is required, the multiple clustered-core processor exploits space redundancy and redundantly executes the program. In this paper, we focus on the trade-off between performance and power, and formulate the trade-off for two dependability schemes we propose.
