This repository stores the source code of FastPath_MP, an FPGA-based multi-path architecture for direct access from FPGA to NVMe SSD. In particular it includes three modules:

• The FastPath_MP FPGA architecture implemented in fpga-design.
• The libfnvme library that implements the C-based API that applications can utilize to communicate with FastPath_MP.
• The modified NVMe driver in the Linux kernel (linux-4.4-zynq) for the Xilinx Zynq 7000 SoC.

The three modules of FastPath_MP are licensed as follows:
