rmNVMe-IP (Random Access & Multi User NVMe IP) is very high performance NVMe Host Controller which is highly optimized for high-IOPS random access applications. rmNVMe-IP supports multiple user interfaces, each user can simultaneously read/write to a single NVMe SSD at the same time.
rmNVMe-IP is designed for the application that requires very random access performance such as real-time sensors data fusion and processing, OS file systems offloading and NVMe SSD tester. By pure hardware logic implementation, rmNVMe-IP is best in class in energy efficient, high performance and low FPGA resource usages for next generation applications.

• NVMe host controller for access one NVMe SSD without CPU and external memory
• Support two users to Write and Read one SSD simultaneously
  • User#0 (Main user): Identify, Shutdown, Read, SMART, and Flush
  • User#1 (Sub user): Write
• Support multiple Write and Read commands for 4Kbyte random access
• Configurable Command Depth of Write and Read command independently: 32 - 256 Commands

• Buffer size depend on Command Depth: 128Kbyte (for 32 Commands) - 1Mbyte (for 256 Commands)
• Simple user interface by using data stream interface
• User clock frequency must be more than or equal to PCIe clock (250MHz for Gen4)
• Operating with Integrated Block for PCI Express by using 4-lane Gen4 (256-bit bus interface)
