A heterogeneous multi-core processor is proposed to achieve real-time dynamic object recognition on HD 720p video streams. The context-aware visual attention model is proposed to reduce the required computing power for HD object recognition based on enhanced attention accuracy. In order to realize real-time execution of the proposed algorithm, the processor(More)
Object recognition processors have been reported for the applications of autonomic vehicle navigation, smart surveillance and unmanned air vehicles (UAVs) [1-3]. Most of the processors adopt a single classifier rather than multiple classifiers even though multi-classifier systems (MCSs) offer more accurate recognition with higher robustness [4]. In(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)
