一种用于 Video Frame Buffer Read IP,另一种用于 Video Frame Buffer Write IP。 我建议使用面向 Video Frame Buffer Write IP 的设计示例,因为 Video Frame Buffer Write IP 和 Video Frame Buffer Read IP 都囊括在其中。 Video Frame Buffer Write IP 设计示例的硬件设计属于非常基础性的设计。 它使用 Video...
1. 上述两个 Video Frame Buffer IP(Read 和 Write)各自的中断输出都连接到处理器。这是前提条件。Video Frame Buffer 是基于中断的 IP。 2. 而这两个 Video Frame Buffer IP 的复位输入则连接至 AXI GPIO IP。这一点至关重要,因为它支持您从处理器执行 IP 软复位。就像所有 HLS IP 一样,只要分辨率改变,...

Lattice Video Frame Buffer IP调试笔记 最近几天在Lattice的EVDK开发板上验证调试了Video Frame Buffer的IP,期间遇到一些问题,在大牛的帮助下,终于解决了,今天来分析总结一下。 1、Lattice Video Frame Buffer IP简单介绍 Lattice Video Frame Buffer(下面简称VFB IP)是一个将外部存储期间作为缓存的,且支持帧率转换和...
36.3. Video Frame Buffer IP Functional Description The IP receives incoming video frames from its Intel FPGA streaming video input and writes them to external memory via an Avalon memory-mapped interface. Received frames are available for output when the Avalon memory-mapped agent accepts the las...
