Ethernet MAC (Media Access Control) sublayer controller and control method thereof

Abstract

The invention relates to an Ethernet MAC sublayer controller and a control method thereof; wherein the bus interface of the Ethernet MAC sublayer controller comprises a first bus interface and a second bus interface; the first bus interface and the second bus interface are connected with a sending FIFO (First Input First Output) module through a first output selector and are connected with a receiving FIFO module through a first input selector; a traffic control module comprises a full duplex traffic control module and a half duplex traffic control module; and the full duplex traffic control module and the half duplex traffic control module are connected with the sending FIFO module through a second output selector, are connected with the receiving FIFO module through a second input selector and are connected with a sending end module and a receiving end module. According to the controller and the method provided by the invention, self-adaptive conversion can be carried out among different rates and different communication states; moreover, a target effect can be realized through limitless program modification; and the flexibility better than a normal MAC sublayer control chip is obtained.

Description

Technical field [0001] The present invention relates to the technical field of Internet communication, in particular to an Ethernet MAC sublayer controller and a control method thereof. Background technique [0002] In the 21st century, the application of the Internet has gradually been applied to the Internet of Things from the traditional PC (personal computer) application. At present, with the rapid development of the Internet of Things, the requirements for the size, power consumption, and hardware scale of the Internet of Things devices are getting higher and higher. , The demand for embedded devices is increasing. The Internet of Things currently mainly relies on the mature technology of Ethernet, but in the process of implementation, the inventor found at least the following problems in the traditional technology: [0003] The traditional Ethernet MAC (Media Access Control) sub-layer control chip is no longer suitable for the application of the Internet of Things equipment,...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide an Ethernet MAC sublayer controller and its control method for the problems of poor flexibility and difficult integration of the Ethernet MAC sublayer control chip in the traditional technology.
