| Abstract: | 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. |
