Abstract: A FLASH-SAR ADC conversion method comprises: at a sampling stage of a FLASH-SAR ADC, sampling an input signal by a SAR ADC module, and at the same time, performing amplification, comparison and high-bit coarse quantization on the input signal by a FLASH ADC module to output a FLASH ADC conversion result, wherein the FLASH ADC conversion result is a temperature code; at a conversion stage of the FLASH-SAR ADC, performing fine quantization on a residual voltage by the SAR ADC module according to the temperature code and the input signal to output a SAR ADC conversion result, and at the same time, sampling a reference voltage or a partial voltage of the reference voltage by FLASH ADC module; and performing encoding on the temperature code and the SAR ADC conversion result to obtain a signal conversion result of the FLASH-SAR ADC.

Abstract: Multiple planes may be used to enhance the video experience in hardware accelerated video in X window systems. A composite window manager, cursor theme, and more than two ARGB format planes may be used. The window manager handles a transparent area. The area that shows the video is defined as a cutout area. Before the window manager redraws a specific window with the cutout area, the area is set to be transparent or translucent. Then the video can be seen through the cutout with or without overlaid translucent graphics. The cursor theme provides opaque cursors.
