As a third-generation universal I/O interconnect technology succeeding ISA and PCI bus, PCI Express has characteristics of lower pin count, higher reliability and faster transfer rate, which makes it a promising prospect. This paper studies PCI Express interface technology of DSP based on KeyStone architecture, and proposes a driver design method aimed at PCI Express interconnection between DSP and...
Both RGB and YCrCb color space are often used in video image processing, along with the wide application of FPGA in the field of video image processing, RGB to YCrCb color space conversion is frequently needed on FPGA. This paper analyzes the process of RGB to YCrCb color space conversion on FPGA, and proposes a fast conversion method using look-up table and pipeline technology. Firstly, on the premise...
Because of the feedback loops caused by iterative operations, MQ arithmetic coder usually acts as the performance bottleneck of the hardware architecture for JPEG2000 algorithm. According to the different features of the loops, this paper adopts different optimizing methods rather than general concurrent techniques to improve the hardware efficiency as well as throughput. Based on careful analysis...
