基于Avalon-ST接口帧读取IP核的设计和应用

研究基于Avalon-ST接口帧读取的IP核设计应用,通过Avalon-ST接口将外部存储中不同格式的帧数据转化为视频流输出。根据Avalon总线协议及Avalon-ST视频协议研究设计方案,使用VerilogHDL语言对模块进行硬件设计,并将实现的模块进行测试。结果表明,该IP核与Altera公司提供的FrameReader模块相比,突破了现有的FrameReader只支持紧缩格式的局限,使其功能更加完善,并且该IP核占用的资源少,工作频率更高,性能得到了优化,实用性更强。

The design and application of frame reader based on Avalon-ST interfaces

Research a IP core design and applications of frame reader based on Avalon-ST interface,IP core read data through the Avalon-ST interfaces from external storage in the frame data in different formats into a video stream output.According to Avalon bus protocol and the Avalon-ST video protocol design,using Verilog HDL language module hardware design,and implementation of the module for testing.The results show that the IP core and frame reader modules provided by the Altera compared to break the existing frame reader limited to tighten format to make it function more perfect,and the IP core occupies less resources,higher operating frequency,performance been optimized,more practical.
