| Abstract(in English) | High speed power gating techniques are useful for reducing leakage power by functional units of CPU core. This paper presents a design and implemetation of functional units on a MIPS R3000 processor with the Row-based power gating technique. Compared with the cell-based power gating technique, which is implemented in our previous work - Geyser-1, the row-based power gating technique can achieve shorter Break-Even time but at a cost of a slightly longer wake-up latency. The post-layout simulation with a benchmark program, JPEG Encoder, shows that with Row-based power gaitng, the leakage power of 4 functional units on MIPS R3000 can be reduced by 28% at 25C; on the other hand, with row-based power gaitng the leakage can be reduced by 26%. |
