Logic Design Solutions Introduces the First NVMe HOST IP on POLARFIRE SoC FPGA
May 04, 2021
Logic Design Solutions (LDS) extends its portfolio of NVME-HOST IPs with the first NVME-HOST IP on POLARFIRE FPGA SoC.
The POLARFIRE FPGA SoC enables designers to address specific market in embedded recording domain.
Per the company, MVMe disks can manage several PCIe links, which allows designers to reach recording speed at more suitable speeds than SATA disk, which have only one link running at 6Gbits maximum, allowing them a recording speed of 500 MBytes/sec. In some cases, SATA disk in RAID 0 can compete NVMe disks in writing and reading speed and in capacity, but at the expense of a need for more space.
All the NVMe protocol is managed by the IP, which is connected to an embedded PCIe Root Port IP in the FPGA. Configuration of the PCIe and of the NVMe are done automatically when power is turned on or on demand after a disk shutdown procedure.
The configuration of the recording session is done by writing to IP registers, using an APB bus. All other data buses are in AXI4 to facilitate the use of the IP.
Therefore, the IP is manageable either by a state machine, whose VHDL source code is provided or by a CPU whose C source code is also provided. The user can start his project directly from ones delivered by LDS.
