A low power voltage management technique is proposed to reduce power consumption for domino circuits. Exploiting a rising and charge-sharing voltage allow the domino circuits to have both high performance and low power consumption. A test chip has been successfully validated to achieve 68% dynamic power consumption and 15% static power consumption respectively using TSMC 0.13um CMOS technology.

This paper presents a single-camera HDR imaging algorithm, which is able to solve all the extreme conditions by controlling the exposure time to get a well-exposed image and then enhancing it. The proposed system is divided into two parts, i.e. single-image HDR imaging technique and an exposure control method. The single-image HDR imaging technique integrates two methods, i.e. Dynamic Local Contrast Enhancement (DLCE) and fuzzy enhancement. The integrated result can handle both glaring region and dark region to exhibit good visibility for extreme conditions. In exposure control method, we utilize local average, camera response function and main object detection to achieve a well-exposed image. Finally, we implement our system on TI OMAP4430 embedded platform. The optimized program is able to achieve about 13 frames per second with VGA resolution. A.
