Abstract

An inter-plate serial communication system comprises a transmitting module and a receiving module, wherein the transmitting module is connected with the receiving module through signals. The transmitting module comprises a transmitted data buffer module and a transmitted data encoding module, wherein the transmitted data buffer module is connected with the transmitted data encoding module through signals. The receiving module comprises a received data dynamic sampling module, a received data decoding module and a received data buffer module, wherein the received data dynamic sampling module is connected with the received data decoding module through signals, and the received data decoding module is connected with the received data buffer module through signals. The transmitted data buffer module comprises a buffer queue module and a transmission control state machine. The inter-plate serial communication system is simple in design, high in communication reliability and communication efficiency, and free of time sequence pressure.

Description

technical field [0001] The invention relates to an inter-board serial communication system and method, in particular to an inter-board serial communication system and method without an associated clock. Background technique [0002] At present, most large-scale communication equipment (such as transmission network equipment, wireless base station equipment, core network equipment, power system control equipment, etc.) include main boards, service boards, dispatching boards, etc. with different functions, and the wiring between each board is through the backplane for data communication. [0003] In some scenarios, faster data communication between boards is required to transmit configuration or other data and control information. Specifically, for example, in a transmission network device, DCN data communication needs to be performed between the mainboard FPGA and the service board FPGA. [0004] In the prior art, some use the Ethernet communication method, some use the SPI...
