The Expert of IP Core & Embedded

raNVMe-IP (Random Access NVMe IP) is the new generation of NVMe-IP series which is intentionally optimized for random access and low latency time. raNVMe-IP can achieve more than 500K IOPS for random write access on high performance NVMe SSD without CPU intervention. Ideal for the application such as Database Search Application which requires multiple access to NVMe SSD with best performance.

Features

• NVMe host controller for access one NVMe SSD without CPU and external memory
• Support up to 32 Write or Read commands for 4 Kbyte random access
• High Performance and Compact resource
  • Write=592KIOPs, Read=226KIOPs
  • Resource usage: 2016ALMs, Block Memory=136KBytes
• Support single command for Identify, Shutdown, SMART and Flush
• Operating the same command at a time, not supporting Write and Read command in the same queue
• Include 128 Kbyte RAM to be data buffer
• Simple user interface by using data streaming interface
• Supported NVMe device
  • Base Class Code:01h (mass storage), Sub Class Code:08h (Non-volatile), Programming Interface:02h (NVMHCI)
  • MPSMIN (Memory Page Size Minimum): 0 (4Kbyte)
  • MDTS (Maximum Data Transfer Size): At least 5 (128 Kbyte) or 0 (no limitation)
  • LBA unit: 512 byte
• User clock frequency must be more than or equal to PCIe clock (250MHz for Gen3)
• Operating with Avalon-ST Hard IP for PCIe by using 4-lane PCIe Gen3 (128-bit bus interface)
• Available reference design on Intel FPGA board with AB18-PCIeX16 or AB16-PCIeXOVR adapter board Available on Mouser
