Abstract

A coding and decoding system and method are disclosed. The coding and decoding method comprises the following steps of: receiving primary data from packages; partitioning the primary data into a first segment and a second segment, wherein the bit number of the first segment is less than the bit number of the second segment; selecting a data segment corresponding to the second segment in a mapping table according to a first state, wherein the first state is opposite to a second state, the second state is one of DC balance and accumulated DC balance, the DC balance is determined by the first segment, and the accumulated DC balance is determined by the first segment and coded data completed in the packages; and sequentially combining the first segment and the data segment so as to generate the coded data. According to the coding and decoding system and method disclosed by the invention, DC balance can be achieved when data is coded and decoded in a high-speed transmission interface, quality of signals received by a receiving terminal can be further improved, and dynamic power consumption of coding and decoding can be reduced.

Description

technical field [0001] The present disclosure relates to a codec system, in particular to a codec system applied to a high-speed transmission interface. Background technique [0002] With the rapid development of communication technology and display technology, the speed and volume of data signal transmission have also been greatly improved. Due to the increase of transmission distance and speed, the signal will be seriously attenuated during transmission. In addition, if the transmitted data signal is continuous 1 (that is, logic high level) and then suddenly switches to 0 (that is, logic low level), or suddenly switches to 1 after continuous 0, the system may be damaged during high-speed transmission. The parasitic capacitance in the circuit has no time to respond, thereby reducing the resolution of the transmitted signal, and causing the receiving end to receive wrong data values. [0003] In order to improve the above problems, the data signal can be coded and decoded ...
