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.

Efficient and optimized approximate GDI full adders based on dynamic threshold CNTFETs for specific least significant bits Research Article

Ayoub SADEGHI, Razieh GHASEMI, Hossein GHASEMIAN, Nabiollah SHIRI,H.ghasemian@sutech.ac.ir

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 599-616 doi: 10.1631/FITEE.2200077

Abstract: Carbon nanotube field-effect transistors (CNTFETs) are reliable alternatives for conventional transistors, especially for use in (AC) based error-resilient digital circuits. In this paper, CNTFET technology and the technique are merged, and three new AC-based full adders (FAs) are presented with 6, 6, and 8 transistors, separately. The is used to attain the optimal performance of the proposed cells by considering the number of tubes and chirality vectors as its variables. The results confirm the circuits’ improvement by about 50% in terms of power-delay-product (PDP) at the cost of area occupation. The Monte Carlo method (MCM) and 32-nm CNTFET technology are used to evaluate the lithographic variations and the stability of the proposed circuits during the fabrication process, in which the higher stability of the proposed circuits compared to those in the literature is observed. The dynamic threshold (DT) technique in the transistors of the proposed circuits amends the possible voltage drop at the outputs. Circuitry performance and error metrics of the proposed circuits nominate them for the least significant bit (LSB) parts of more complex arithmetic circuits such as multipliers.

Gao Xueping,Chen Hong,Song Huifang

Strategic Study of CAE 2011, Volume 13, Issue 12,   Pages 63-67

Abstract:

In thermally stratified reservoir, a multi-level intake structure is usually adopted in hydropower station to reduce the negative effect of releasing lower-temperature water to the environment in downstream reach. And a simple and practical formula of water temperature released is need. In this paper, based on Nuozhadu Hydropower Station, a model test is conducted to model the thermal stratification of this reservoir, and measure the temperature of water released from the intake structure. A prediction formula of water temperature released is put forward based on the experimental data. The formula is validated by the experimental results of water temperature released from the intakes of Jinping No.1 Hydropower Station.
