摘要： A circuit design system, methodology, and software are disclosed for generating circuit capable of consuming less dynamic power. In particular, the circuit design methodology entails modifying an initial circuit design including a clock network coupled to a plurality of edge-triggered flip-flops to generate a modified circuit design that uses pulsed latches driven by pulse generators in place of at least some of the flip-flops. Since pulsed latches use less dynamic power than edge-triggered flip-flops, the modified circuit may consume less dynamic power. The circuit design methodology may further entail adding delay cells for balancing the clock network to compensate for timing effects caused by the insertion of pulse generators. Additionally, the methodology may further include cloning of forbidden clock paths to make more flip-flops eligible for pulsed latch replacement.

摘要： A method and an apparatus for over-driving a liquid crystal display (LCD) are provided, which are suitable for compensating a gray level brightness of the LCD. The method includes the following steps. Firstly, a data buffer unit outputs a current frame data. Then, the current frame data is stored into a frame memory unit, and the frame memory unit outputs a previous frame data. Next, several look-up tables (LUTs) are searched for a driving voltage in a corresponding LUT according to the current frame data and the previous frame data. Afterward, a position scanning unit receives the current frame data to determine a current position. Finally, a multiplexer outputs the corresponding driving voltage at the current position. Thus, a display panel has the same gray level brightness in upper, middle, and lower portions thereof, thereby avoiding ghosting.
