Title:

SMYLEvideo distributed stream processing heterogeneous Manycore architecture for Video Mining Applications

Abstract:

Our objective is to provide a scalable Manycore processor to enable software based real-time processing of various Video Mining applications for several embedded systems, such as auto-motives, digital cameras, digital TVs, video surveillance systems, etc. We intensively worked on architecture-algorithm co-design, and designed a distributed processing application software based on Kahn Process Networks (KPN) and a Video Mining application domain specific scalable manycore processor architecture SMYLEvideo with having clustered heterogeneous cores. We improved performance scalability of Manycore with minimizing inter-process communication overhead by an innovative HW/SW mechanism implemented on each core and with special inter-core event communication network. We also reduced external memory access bandwidth and capacity requirement, that also limit the performance scalability of Manycore, by optimizing data passing granularity of distributed processing software, and by utilizing on chip core to core data passing mechanism. We also improved energy-efficiency and performance per cost with required reducing hardware resources, such as datapath width of each data processing core as well as the number of cores. As a result we architected a heterogeneous manycore SMYLEvideo with 64-bit and 256-bit data processing cores with having Video Mining application domain specific instruction extensions. The SMYLEvideo runs at only 100MHz, however, for example it can scale its image recognition performance based on SIFT algorithm from 15fps, 30fps, 60fps with scaling the number of cores from one master core plus 10 cores in 2 clusters, 20 cores in 4 clusters, up to 40 cores in 8 clusters, respectively.
