hdl_example

SNAP HDL EXAMPLE

The hdl_example is a multi function example. The hardware is written in VHDL, the software in C.

Hardware

The hardware part implements the following core functions:

• A counter function
• A function that copies data from and to the Host Memory
• A function that copies data from and to the DDR Memory (on the FPGA Card)
• A function that copies data from and to the NVMe
• A set memory and check memory function

Dependent on the SNAP configuration the necessary interfaces will be added to or removed from the action.

Software

• snap_example

  • Count down mode
  • Copy from Host Memory to Host Memory.
  • Copy from Host Memory to DDR Memory (FPGA Card).
  • Copy from DDR Memory (FPGA Card) to Host Memory.
  • Copy from DDR Memory to DDR Memory (both on FPGA Card).

• snap_example_set

  • Test tool to Set Memory in Host or DDR Memory (FPGA Card)

• snap_example_ddr

  • Tool to check DDR Memory (FPGA Card)

• snap_example_nvme

  • Tool to check NVMe

• snap_example_qnvme

  • Tool to check NVMe, using the NVMe host controller's queue to enqueue multiple requests.
