—Fractional motion estimation (FME) significantly enhances video compression efficiency, but its high computational complexity also limits the real-time processing capability. In this paper, we present a VLSI implementation of FME design in High Efficiency Video Coding (HEVC) for ultra-high definition video (Ultra-HD) applications. We firstly propose a(More)
—Spectral unmixing amounts to automatically finding the signatures of pure spectral components (called endmembers in the hyperspectral imaging literature) and their associated abundance fractions in each pixel of the hyperspectral image. Many algorithms have been proposed to automatically find spectral endmembers in hyperspectral data sets. Perhaps one of(More)
—Context-based Adaptive Binary Arithmetic Coding (CABAC) is a well known bottleneck in H.264/AVC encoder. Despite its high performance, the tight feedback loops make it difficult to parallelize. Most researchers are concerned about multi-bin processing regardless of the pipeline design. But without pipeline, the overall performance is greatly limited. In(More)
In the field of big data applications, lossless data compression and decompression can play an important role in improving the data center's efficiency in storage and distribution of data. To avoid becoming a performance bottleneck, they must be accelerated to have a capability of high speed data processing. As FPGAs begin to be deployed as compute(More)

Bacterial persisters, usually slow-growing, non-replicating cells highly tolerant to antibiotics, play a crucial role contributing to the recalcitrance of chronic infections and treatment failure. Understanding the molecular mechanism of persister cells formation and maintenance would obviously inspire the discovery of new antibiotics. The significant(More)
