Abstract

The invention implementation provides a serial transmission method and system based on 8B/10B coder and decoder and relates to the field of the information and communication technologies (ICT). The method comprises the steps that serial data transmitter transforms the 16 bit parallel data with particular format to 20 bit parallel data after 8B/10B coding two times, serial data transmitter transforms 20 bit parallel data to high-speed serial data stream and then transmits the high-speed serial data stream to serial data receiving terminal, the serial data receiving terminal receives the high-speed serial data stream and transforms the high-speed serial data stream to 20 bit parallel data, later the serial data receiving terminal obtains the 16 bit parallel data with particular format after two times of 8B/10B decoding to 20 bit parallel data. The invention implementation can realize serial transmission of the data with 2711 format and make up the transmission problem that existing FPGA build-in hard kernel cannot satisfy the serial transmission with 2711 format. The invention implementation not only lows down the communication cost of serial transmission after focusing on the defects of data development specialized chip with 2711 format, but also simplifies the structure of FPGA without arranging a plurality of universal pins for connecting specialized chip.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a serial transmission method and system based on 8B / 10B encoding and decoding. Background technique [0002] At present, 8B / 10B encoding and decoding are widely used in serial data transmission. However, the existing FPGA built-in hard core is basically only suitable for commonly used protocols, such as: Ethernet protocol, which is not flexible enough to meet the data format of specific fields. Requirements, such as: 2711 format data. At present, the method of realizing serial transmission of 2711 format data on FPGA is generally as follows: FPGA provides a large number of pins, connects a dedicated chip for 2711 format data through a large number of pins, and then uses the dedicated chip to realize 2711 format The serial transmission of data, this method not only needs to develop a special chip for the characters of the 2711 format data, the cost is high, but ...
