Configuration and management of the image gateway based on the embedded system

In order to realize the configuration convenience and management standardization of the image gateway, this paper adopts a scheme of configuration and management by using the embedded system and the host computer software. The scheme uses K60 (NXP Freescale MK60DN512VLQ10) as the master chip, transplants RT-Thread, a real-time operating system, and a lightweight protocol stack LwIP, which runs TCP / UDP Socket service, listens to the host computer command. The embedded system is connected with the core processor FPGA (Field Programmable Gate Array) through the RMII and the UART interfaces. To realize the configuration of the image gateway, the embedded system reads the network packets from FPGA through the RMII interface and sends the security rules to FPGA through the UART.
