| Abstract(in English) | A heterogeneous multi-core processor, which is consists of the combination of fine-grained power gating for split ALU and coarse-grain power gating for cores, is designed and evaluated. Although the high-perfomance core (HP-Core) and the low-power core (LP-Core) run with the same ISA, the HP-Core is a Superscaler with higher clock frequency, compared with the LP-Core. Each core shares 16KB L1 Cache and TLB, and is designed using Fujitsu 65nm CMOS technology. As a result, the perfomance of HP-Core increased by 24%. The leakage power is reduced by 46% for executing Dijkstra and Blowfish, while the power comsuption is increased by 63% for Quick Sort and JPEG. Area overhead is 9.2%. |
