Xilinx FPGA NVMe主机控制器IP, 高性能版本
<div class='showpostmsg'><p align="center">NVMe Host Controller IP</p><ol>
<li ><a name="_Toc155199081"> 介绍</a></li>
</ol>
<p >NVMe Host Controller IP可以连接高速存储PCIe SSD,无需CPU和外部存储器,自动加速处理所有的NVMe协议命令,具备独立的数据写入AXI4-Stream/FIFO接口和数据读取AXI4-Stream/FIFO接口,非常适合于超高容量和超高性能的应用。此外,NVMe Host Controller IP支持RAID存储,从而可实现更高存储性能和存储容量。</p>
<p >无需CPU,NVMe Host Controller IP自动执行对PCIe SSD的PCIe设备枚举和配置、NVMe控制器识别和初始化、NVMe队列设置和初始化,实现必须以及可选的NVMe Admin Command Set和NVM Command Set,实现对PCIe SSD的复位/断电管理、IO(Page)读写、DMA读写和数据擦除功能,提供用户一个简单高效的接口实现高性能存储解决方案。</p>
<p >NVMe Host Controller IP DMA读写的顺序传输长度可以配置,最小是4K-Byte,最大是512K-Byte。顺序传输长度配置为4K-Byte,NVMe Host Controller IP所消耗的BRAM最少,但是可以达到CrystalDiskMark测试软件RND4K Q32T16测试模式下的读写性能。顺序传输长度配置为128K-Byte,NVMe Host Controller IP所消耗的BRAM比较多,可以达到CrystalDiskMark测试软件SEQ128K Q32T1测试模式下的读写性能。</p>
<p >针对多路数据通道访问PCIe SSD,使用NVMe的多队列特性,NVMe Host Controller IP支持灵活配置DMA读写的通道个数,按照NVMe队列优先级仲裁机制,实现多个DMA通道对同一块PCIe SSD的高效访问,从而达到多路数据通道访问的并行需求和QoS要求。</p>
