Abstract: A method for adjusting sharpness and brightness of a digital image. In this method, an image function is first inputted into a processor. The image function comprises a plurality of control parameters. Next, the control parameter values of the control parameters are set, and then each of the pixels is sequentially leaded into the image function according to the control parameter value so as to perform the corresponding operation for adjusting the sharpness and brightness of the image. Finally, the adjusted image is outputted. Therefore, the two processes in the prior art, one for adjusting the brightness, the other for the sharpness, are merged into one process so that the design of the hardware circuit is simplified and the required memory space is reduced.

Abstract: An approach to enhance the noise immunity of high-speed digital signals by means of a resonance-free environment is developed. Resonance detuning is achieved by appropriately reshaping the layout of the power/ground planes. Resonant properties of the power distribution system, including resonant frequencies and field distribution profiles, were characterized with frequency-domain simulations. Analysis of the resonant field profiles reveals that the electric field distribution of the dominant mode normally concentrates in the vicinity of the plane edge. Therefore, resonance can be effectively tuned out of the operating frequency range through boundary configuring. In addition, it is shown that variation of the quality factor with the external probe position provides a means to monitor and construct the resonant field distribution. Physical mechanism responsible for this unique property is clarified from the perspective of probe coupling. A Y-shaped layout is reshaped to effectively realize a resonance-free operating environment.

Abstract: The invention provides a graphic engine and a method that reduces the idle time of the graphic engine by validity test. The validity test is performed when the back buffer is full and the graphic engine continues to write a primitive into a front buffer. The validity test compares the maximum Y-coordinate of the primitive with the Y-coordinate of the current scan line. If the maximum Y-coordinate of the primitive is less than the Y-coordinate of the current scan line, the graphic engine keeps on executing the primitive processing procedure. On the other hand, if the maximum Y-coordinate of the primitive is greater than or equal to the Y-coordinate of the current scan line, the graphic engine halts the primitive processing procedure until the maximum Y-coordinate of the primitive is less than the Y-coordinate of the current scan line.
