The Expert of IP Core & Embedded

NVMeTCP IP is the standalone host side NVMe Over Fabric (NVMe/TCP) controller with no CPU and external memory required. Enabling very high-performance remote access to NVMe-oF Storage Server by simple user logic. Greatly reduce design complexity and development time. Allowing your FPGA Card/Board to get access to the existing NVMe-oF storage infrastructure remotely and directly over FPGA’s network interface with maximum possible performance.
This IP core license includes the reference design for AMD FPGA boards. It helps you to reduce development time and cost.

Features

Application example

	Automotive In modern vehicles, FPGAs often handle data from sensors, cameras, and radar systems. With our NVMeTCP IP Core, this data can be processed in real-time and then sent via 10G or 25G Ethernet to a remote NVMeTCP storage server. This approach not only saves space and power on the vehicle but also ensures that massive amounts of data are stored reliably and efficiently. More solution
	Aerospace At satellite ground stations, FPGAs manage the downlink of data from satellites. By utilizing the NVMeTCP IP Core, this critical data can be quickly transmitted over 10G or 25G Ethernet to remote storage servers. This method allows for the secure and efficient storage of large volumes of satellite data without compromising on performance or scalability. More solution
