Problems solved by technology

Using this method not only greatly increases the workload of post-debugging, but also in actual application, the transmission delay changes due to differences in circuit board processing batches and design modifications, and the test delay is adjusted at the receiving end method will not guarantee reliable reception of data under all conditions
So, the above solution did not achieve the desired effect

Embodiment Construction

[0019] Various preferred embodiments of the present invention will be described in detail below.

[0020] The design idea of ​​the present invention is to add two sets of sending and receiving triggers on the backplane side of the hardware board, and these two sets of triggers will cut the time delay from the sending end to the receiving end, so that the time delay will not accumulate, and the system timing During the design, we only need to pay attention to the reliability of the transceiver trigger and the delay of the backplane, and the delay coordination of the own devices on the hardware board is controlled by the hardware board. By adopting this design method, the data delay fluctuation range from the sending end to the receiving end can be reduced, and the system synchronization design becomes easy to realize, thus providing a simple structure, easy to implement, An effective backplane interface that is low in cost and can guarantee the quality of data transmission is d...

Abstract

The invention discloses a backplane interface of hardware board that lies on the hardware board. Business data processing unit of the hardware board transmits business data with backplane through the backplane interface. it is characterized in that the backplane interface includes a group of sending trigger used to transmit business data that hardware board pre-sends to the backplane; a group of receiving trigger used to collect and receive data from the backplane, business data processing unit sent to the hardware board. The invention segments the delay from the sender to the receiver through increasing two groups of triggers, in these circumstances, the delay doesn't accumulate, only need to be concerned about the reliability of delay of the receiving and sending trigger and backplane.

Description

technical field [0001] The invention relates to the field of communication, in particular to a design scheme of a backplane interface capable of eliminating the correlation of slots of hardware boards. Background technique [0002] In the communication field, switches, routers, and various transmission equipment usually adopt a chassis system structure with multiple interface card slots. The hardware boards in each slot are connected to the backplane through the backplane socket interface, so the connection between each hardware board Data information can be transmitted through the backplane bus, and its principle structure is shown in Figure 1. In the process of data transmission, the hardware boards of each slot share the same clock source, and the in-phase clock sent by the system clock unit (the system clock CLK1, CLK2, ... CLKN) to complete the sending and receiving of data. [0003] When the device adopts the system structure shown in Figure 1, if the hardware board ...
