Logic Design Solutions: NVME-Host-Recorder-ITX-Z7 IP

IP is manageable either by state machine, whose VHDL source code provided or by CPU whose C source code is also provided.

The NVME-Host-Recorder-ITX-Z7 IP from Logic Design Solutions (LDS) completes an existing family of SATA Recorder IP in order to provide a complete panoply in embedded recording domain.

MVMe disks can manage several PCIe links, which allows them to reach recording speed faster than SATA disk, which have only one link running at 6Gb maximum, allowing them a recording speed of 500MB/s.

Nevertheless in some cases, SATA disk in RAID-0 can compete NVMe disks in writing and reading speed and in capacity, but at the expense obviously of a need for more space.

Simple to use
The company has for many years acquired expertise in the field of embedded recording, so LDS has taken care to offer an NVMe Host Recorder IP which is easy to use for both those who start in the field of NVMe disks and the more experienced.

Thus 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 AXI Lite bus. All other data buses are in AXI4 to facilitate the use of the IP.

Thus, 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 the projects delivered by LDS.
