Embodiment Construction

[0028] The embodiment of the present invention provides a bus interface for realizing hot plugging. The structural diagram of the bus interface is as follows: figure 1 As shown, including the connector and the voltage stabilization filter unit, where:

[0029] Connectors are used to realize the hot plugging of ground wires, power wires and signal wires, connect the card and the bus, and control the power-on sequence of the cards according to the length and position of the pins;

[0030] The pins of the connector include pins connected to ground wires, pins connected to power lines and pins connected to signal lines;

[0031] The voltage stabilizing filter unit is used to connect with the pin wire connecting the power line, and keep the input voltage of the card stable when the card is hot-swapped;

[0032] The card is a master card or a slave card.

[0033] The schematic diagram of the structure of the connector is as figure 2 As shown, the pins connected to the ground wir...

Abstract

An embodiment of the invention provides a bus interface for realizing hot plug and a method thereof. The hot plug can be realized through the electrifying sequence of restricting cards without a special hot plug chip. The invention settles the problem that the special hot plug chip is required for realizing hot plug in prior art. The hot plug is better realized and the bus stability is greatly increased.

Description

technical field [0001] The invention relates to the communication field, in particular to a bus interface and method for realizing hot plugging. Background technique [0002] High-speed serial bus is used for high-speed data transmission between cards (including master card and slave card). In practical applications, it is often necessary to hot-swap the card, which can quickly change the card on the bus and is easy to use; most of the existing bus interfaces do not support the hot-swappable function, but the bus interface that supports the hot-swappable function Most of them use dedicated hot-swappable chips, which can strictly control the power-on sequence, and the implementation is troublesome. Usually, the price of dedicated hot-swappable chips is relatively high, and the cost of the card increases. [0003] Therefore, the defect of the prior art is that a dedicated hot-swappable chip needs to be used to realize hot-swapping, the power-on sequence is strictly controlled...
