In view of the shortcomings of low-latency data transmission and fast reading and writing of the current SATA interface

combined with the requirement of space application to the host controller

this paper proposed a FPGA implementation scheme for NVMe high-speed storage. It takes NVMe 1.3a protocol for reference and is implemented on the basis of ZC706 evaluation board of Xilinx with modular design concept in VHDL language. According to the simulation verification

it shows that the controller IP core can realize many operations

such as reading

writing

device reset and identification. It can be applied to embedded storage system.
