Optimal Design of Video Decoding System Based on Nios Ⅱ Soft-Core
研究了基于嵌入式Nios Ⅱ软核的MPEG-4视频解码系统的设计优化,以期提高便携式多媒体播放器视频解码的综合性能.提出了在可编程片上系统(System on a programmable chip,SOPC)中软硬件协同设计方案,通过研究二维离散余弦逆变换、运动补偿、颜色空间转换的硬件IP核优化设计与实现,构建基于Nios Ⅱ软核软硬件协同设计的视频解码系统.以Altera型号EP2C35F672C8的FPGA为核心的SOPC系统测试结果表明,…查看全部>>
To improve the comprehensive performance of portable media player video decoding, the optimal design of MPEG-4 video decoding system based on embedded Nios II soft-core is studied. And the design scheme of software and hardware co-design in system on a programmable chip (SOPC) is also proposed. By studying hardware intellectual property (IP) core design optimization and implementation of the two-dimensional inverse discrete cosine transform (2D IDCT), …查看全部>>
