Continuing from the previous article, a typical low power design in digital chips is the addition of a clock gate. Another method is through parallel and pipelining techniques. Parallel and Pipelining The prominent advantage of hardware description languages is the parallelism in instruction execution. Multiple statements can process several signal data in parallel within the … Read more
With the increase in device density and clock frequency of chips under advanced processes, power consumption has also significantly increased. At the same time, the supply voltage and transistor threshold voltage have been reduced, leading to significant leakage current. High power consumption can cause excessive temperature during device operation, reducing reliability due to electromigration and … Read more
Leakage power consumption has increased with each generation of CMOS technology. This leakage power not only poses a serious challenge for battery-powered or portable products but is also becoming an issue that wired devices such as servers, routers, and set-top boxes must address. To reduce the total leakage power consumption of chips, it is best … Read more
State Retention and Restoration Methods Continuing from the previous text Low Power Design Methods – Power Gating Design (Part 1) Low Power Design Methods – Power Gating Design (Part 2) Given the power switch structure and isolation strategy, power gating can be applied to logic blocks. However, unless a retention strategy is employed, all state … Read more
