Description
The LDS NVME HOST IP has been done for beginners and experts in NVMe to drive NVMe PCIe SSD.
- The LDS NVME HOST IP provides two interfaces :
- One CPU interface for long sequential recording or reading.
- One FIFO interface for I/O intensive data transfer.
The register file interface simplifies the management of the IP for CPU interface or State Machine interface using Avalon bus:
- PCIe RP and EP register configuration is done automatically.
- NVMe register configuration is done automatically.
- Able to manage 8 Name Spaces.
- Able to manage until 16 IO Queue to able Multi-users.
- Each IO Queue is independent.
- Able to manage 512Bytes or 4096Bytes sector size.
- Able to run nearly all Admin commands in parallel of IO Queue.
- Some IO commands are already pre-defined to ease the use of the IP.
- Configurable IO Queue buffer size to fit user memory requirement: 32KB, 64KB, 128KB, 256KB, 512KB or 1024KB.
- Able to read all PCIe RP and EP registers.
- Able to stop the current command.
- Able to manage low data rate in reading.
- Easy connection to embedded Root Port R-Tile PCIe IP through Avalon bus.
- FAT32 / EXFAT available as an option.
The source code format is available for ease of customisation. The customisation can be done by Logic Design Solutions, and DO254 documentation is available on request.
This IP can be customised according to specific needs (application-specific requirements). Any other pre-designed functions can be integrated into the FPGA. FPGA density and I/O requirements can be defined according to customer specification.
