摘要
提出了一种基于NiosII多核处理器的JPEG解码方法,主要介绍了双核NiosII处理器系统的设计方法,以及该系统对JPEG解码的并行处理过程,并且简要分析了JPEG解码中YUV到RGB转换的自定义功能模块对系统性能的影响。实验证明,该设计方法具有结构简单、处理速度快等优点,因而具有很好的推广价值。
In this paper, a measure of JPEG decoding based on a multi-core processor-based of NiosII is introduced, a method of design in dual-core processor system is mainly introduced, and the system for parallel processing of JPEG decoding process and a brief analysis of the JPEG decoding YUV to RGB conversion custom function modules on the system performance. Experiments show that the design method is simple in structure, processing speed, etc., and thus has a very good promotional value.
