Abstract

The invention proposes an Ethernet communication system and an Ethernet communication method based on a multi-media card / security digital card (MMC / SD) interface. The communication system comprises at least one master equipment and at least one slave equipment, wherein the at least one master equipment and the at least one slave equipment are connected through the MMC / SD interface and are mutually communicated on Ethernet. According to the Ethernet communication system and the Ethernet communication method based on the MMC / SD interface, which are disclosed by the invention, equipment with the MMC / SD interface becomes a node in a network, so that the application field of the same type of equipment is greatly expanded.

Description

technical field [0001] The present invention relates to an Ethernet communication system and method, more specifically, to an Ethernet communication system and method based on an MMC / SD interface. Background technique [0002] At present, with the increasing popularity of smart card applications, devices based on MMC / SD (Multimedia Card / Secure Digital Card) interfaces are widely used in various fields. Existing devices with MMC / SD interfaces mainly focus on terminal devices (master devices), such as computers and mobile phones, and memory cards (slave devices), such as MMC cards and SD cards. Usually, the MMC / SD interface is used as a channel for the master device to read and write data on the slave device, that is, it is a master-slave mode (in other words, all communications are initiated by the master device). figure 1 It is a flow chart of signaling interaction of a typical MMC / SD interface. Such as figure 1 As shown, the master device sends a CMD command, and then th...
