Wearable head-mounted display (HMD) smart devices are emerging as a smartphone substitute due to their ease of use and suitability for advanced applications, such as gaming and augmented reality (AR) [1–2]. Most current HMD systems suffer from: 1) a lack of rich user interfaces, 2) short battery life, and 3) heavy weight. Although current HMDs (e.g. Google Glass) use a touch panel and voice commands...
A hybrid radix-4/-8 multiplier is proposed for portable multimedia applications that demand high speed and low energy operation. Depending on the input pattern, the multiplier operates in the radix-8 mode in 56% of the input cases for low power, but reverts to the radix-4 mode in 44% of the slower input cases for high speed. For this, a mode detection circuit determines the mode signal from the input...
A heterogeneous many-core object recognition processor is proposed to realize robust and efficient object recognition on real-time video of cluttered scenes. Unlike previous approaches that simply aimed for high GOPS/W, we aim to achieve high Effective GOPS/W, or EGOPS/W, which only counts operations carried out on meaningful regions of an input image. This is achieved by the Unified Visual Attention...
