Moving object recognition in a video stream is crucial for applications such as unmanned aerial vehicles (UAVs) and mobile augmented reality that require robust and fast recognition in the presence of dynamic camera noise. Devices in such applications suffer from severe motion/camera blur noise in low-light conditions due to low-sensitivity CMOS image(More)
—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(More)
A 36 Heterogeneous multicore processor is proposed to accelerate recognition-based markerless augmented reality. To enable a real-time operation of the proposed augmented reality, task-level pipelined multicore architecture with DLP/TLP optimized SIMD processing elements is implemented. In addition, the multicore employs a congestion-aware network-on-chip(More)
