HAL-ASOS - hardware assisted Linux for application specific operating system
Silva, Vítor Alberto TeixeiraO ecossistema de sistemas embebidos de hoje tornou-se enorme, cobrindo vários e diferentes sistemas, exigindo desempenho e mobilidade completa enquanto atingem autonomias de bateria cada vez maiores. Mas a crescente frequência de relógio que resultou em dispositivos cada vez mais rápidos começou a estagnar antes dos transístores pararem de encolher. Plataformas Field Programmable Gate Array (FPGA) são uma soluç...
HAL-ASOS accelerator model: evolutive elasticity by design
Silva, Vítor Alberto Teixeira; Pinto, Paulo; Cardoso, Paulo; Cabral, Jorge; Tavares, AdrianoTo address the integration of software threads and hardware accelerators into the Linux Operating System (OS) programming models, an accelerator architecture is proposed, based on micro-programmable hardware system calls, which fully export these resources into the Linux OS user-space through a design-specific virtual file system. The proposed HAL-ASOS accelerator model is split into a user-defined Hardware Tas...
Application specific architecture for hardware accelerating HOG-SVM to achieve ...
Ranawaka, Piyumal; Ekpanyapong, Mongkol; Tavares, Adriano; Cabral, Jorge; Athikulwongse, Krit; Silva, Vítor Alberto TeixeiraComputer Vision is an emerging field with diverse applications which encompasses many algorithms with heavy computations. Histogram of Oriented Gradients-Support Vector Machine (HOG-SVM) is one such versatile algorithm used for object detection and image classification despite it's heavy computation load. Processing such an algorithm in real time with adequate throughput is a challenging task for a general purp...
