Hello hero, welcome to the FPGA technology world. The world is vast, and meeting each other is fate. Great heroes can follow the FPGA technology world and obtain other interested resources in the "Wandering the World" and "Acting Righteousness" sections, or enjoy drinking and chatting together.
Today, I bring you the design of an FPGA based Ethernet controller (MAC) for Daxia. Due to its length, it will be divided into three parts. Today we bring the first article, the previous one, on the basic principles of Ethernet and the basic framework of Ethernet Controller (MAC). Without further ado, let's proceed with the shipment.
For the convenience of reference and learning, hyperlinks are also provided here for the last two articles:

At present, the Internet has greatly changed our production and life. Correspondingly, in the research and development of embedded systems, there is an increasing emphasis on network functionality. Embedded systems are no longer limited to isolated control and processing units, but are moving towards network integration, thereby achieving centralized control and information sharing among multiple systems.
The development and application of Ethernet technology in embedded systems has become one of the current hot topics in the field of embedded research. On the one hand, compared with traditional RS-485, CAN, etc., Ethernet is faster, more versatile, and can also be directly connected to the Internet, providing a wider range of remote access; In addition, the TCP/IP protocol stack, which has been appropriately tailored and optimized, can also fully meet the needs of industrial applications. On the other hand, compared to emerging buses such as USB 2.0 and IEEE 1394, Ethernet technology has significant advantages in transmission distance, wiring cost, and the universality of control software.
Embedded systems based on Ethernet have promising application prospects in the following areas:
Industry: Industrial control, network instruments, remote distributed data collection
Home automation: smart homes, information appliances, home gateways
• Business: Remote sales platform, intelligent vending machines, public SIM card issuance system
Environmental protection: monitoring of water and air pollution, flood control system and soil and water quality monitoring, dam safety
• Other: traffic management, vehicle navigation, automatic meter reading
Therefore, when designing various embedded application systems using FPGA, it is necessary to consider providing Ethernet interfaces for the system.
