Power-efficient dual-edge implicit pulse-triggered flip-flop with an embedded clock-gating scheme Article

Liang GENG,Ji-zhong SHEN,Cong-yuan XU

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 9, Pages 962-972 doi: 10.1631/FITEE.1500293

Abstract: A novel dual-edge implicit pulse-triggered flip-flop with an embedded clock-gating scheme (DIFF-CGS)is proposed, which employs a transmission-gate-logic (TGL) based clock-gating scheme in the pulse generationThis scheme conditionally disables the inverter chain when the input data are kept unchanged, so redundanttransitions of delayed clock signals and internal nodes of the latch are all eliminated, leading to

Dynamic power-gating for leakage power reduction in FPGAs Research Article

Hadi JAHANIRAD,h.jahanirad@uok.ac.ir

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4, Pages 582-598 doi: 10.1631/FITEE.2200084

Abstract: devices have become widespread in electronic systems due to their low design costs and reconfigurability. In battery-restricted applications such as handheld electronics systems, low-power FPGAs are in great demand. almost equals dynamic power in modern integrated circuit technologies, so the reduction of leads to significant energy savings. We propose a power-efficient architecture for static random access memory (SRAM) based FPGAs, in which two modes (active mode and sleep mode) are defined for each module. In sleep mode, ultra-low is consumed by the module. The module mode changes dynamically from sleep mode to active mode when module outputs evaluate for new input vectors. After producing the correct outputs, the module returns to sleep mode. The proposed circuit design reduces the consumption in both active and sleep modes. The proposed low-leakage FPGA architecture is compared with state-of-the-art architectures by implementing Microelectronics Center of North Carolina (MCNC) benchmark circuits on FPGA-SPICE software. Simulation results show an approximately 95% reduction in consumption in sleep mode. Moreover, the total power consumption (leakage+dynamic power consumption) is reduced by more than 15% compared with that of the best previous design. The average area overhead (4.26%) is less than those of other designs.
