    摘要: Provided is a low-power clock gating circuit using a Multi-Threshold CMOS (MTCMOS) technique. The low-power clock gating circuit includes a latch circuit of an input stage and an AND gate circuit of an output stage, in which power consumption caused by leakage current in the clock gating circuit is reduced in a sleep mode, and supply of a clock to a unused device of a targeted logic circuit is prevented by the control of a clock enable signal in an active mode, thereby reducing power consumption. The low-power clock gating circuit using an MTCMOS technique uses devices having a low threshold voltage and devices having a high threshold voltage, which makes it possible to implement a high-speed, low-power circuit, unlike a conventional clock gating circuit using a single threshold voltage.

    摘要: Provided is a parallel processor for supporting a floating-point operation. The parallel processor has a flexible structure for easy development of a parallel algorithm involving multimedia computing, requires low hardware cost, and consumes low power. To support floating-point operations, the parallel processor uses floating-point accumulators and a flag for floating-point multiplication. Using the parallel processor, it is possible to process a geometric transformation operation in a 3-dimensional (3D) graphics process at low cost. Also, the cost of a bus width for instructions can be minimized by a partitioned Single-Instruction Multiple-Data (SIMD) method and a method of conditionally executing instructions.

Further, the active piezoelectric energy harvester can precisely adjust the resonance frequency even when the frequency of vibration varies over time as in a real natural vibration environment or when it is degraded to undergo a variation in its own resonance frequency, and thus can continuously maintain optimal energy conversion characteristics.
