Method and device for serialization and deserialization

Abstract

The invention discloses a method for serialization and deserialization, comprising the following steps: the number N of channels is taken as variable, a frame format encoding serial data is set; a local reception end determines the frame head of the received serial data according to the set frame format and converts the serial data into N-bit parallel data; the parallel data is analyzed according to the set frame format so as to obtain a link state and the N-bit parallel data is output; a local transmission end encodes the local parallel data according to the set frame format, and the parallel data corresponding to the frame format is output according to the link state resulted from the analysis of the local reception end; and the parallel data is converted into the serial data and frequency-doubling high-speed clock is utilized to output the serial data. The invention further discloses a device for serialization and deserialization; by adopting the method and the device, chips with the single-chip SERDES function can be used for the mutual conversion between parallel signals and serial signals of the different number of channels, and meanwhile, consumptive cost of users is reduced.

Description

technical field [0001] The invention relates to serial communication technology, in particular to a method and device for serialization and deserialization. Background technique [0002] With the development of communication technology, people's demand for information flow continues to increase, while the traditional parallel interface technology has become a bottleneck to further increase the data transmission rate. With the improvement of chip processing speed and the development and wide application of high-speed optical fiber communication technology, the serial communication technology——Serializer / Deserializer (SERDES) technology is gradually replacing the traditional parallel interface technology and has become a popular High-speed interface technology. [0003] SERDES technology is a time-division multiplexing and point-to-point communication technology. At the sending end, multi-channel, that is, multi-channel low-speed parallel signals are converted into high-speed...

Problems solved by technology

However, a chip with SERDES function produced by a chip manufacturer can only meet the serial-to-parallel conversion of a data link with a fixed ratio, and does not support the serial-to-parallel conversion of data links with other ratios. For example, the serial-to-parallel conversion of a certain SERDES function The chip is used for the serial-to-parallel conversion of the 8:1 data link. If the user wants to change the 8-channel parallel signal to the 10-channel parallel signal, he can only repurchase the 10:1 SERDES function chip. The original 8:1 Chips with SERDES functions can no longer be used. It can be seen that the scope of application of chips with SERDES functions is not flexible enough, and the consumption cost of users is very high.
