Embodiment Construction

[0014] The invention will be described in detail below with reference to the accompanying drawings and examples. The following embodiments may be combined with another embodiment of no conflict.

[0015] like figure 1 , The encoding method of an embodiment of the present invention comprises:

[0016] S1: first bit stream of the quality determination.

[0017] The first bit stream may be unencoded data bits which can be transmitted according to the actual needs, for example, 8 bits, 16 bits and so on. Quality determination may satisfy the predetermined quality criteria for judging the quality of the first bit stream. The quality criteria may be associated with successive bits of the same logic value in the first bit stream. Generally, to meet the same quality standards of the first logical value in the bit stream consecutive bits less than a threshold value, the size of the threshold may be associated with the first stream of bits, for example bits of the first bit stream half plus...

Abstract

Disclosed in the present application is a coding method. The method comprises: performing quality determination on a first bit stream; if the first bit stream satisfies a pre-set quality standard, combining the first bit steam and an identifier bit to output a second bit stream; if the first bit stream does not satisfy the pre-set quality standard, performing a logic operation on the first bit stream to output a third bit stream, the number of bits of the third bit stream being greater than that of the first bit stream. Further disclosed in the present application are a coding apparatus and a readable storage medium.

Description

Technical field [0001] The present invention relates to the field of data transmission, particularly to a coding method, apparatus and readable storage medium. Background technique [0002] In serial data transmission, data transmission may be encoded into the code stream includes the clock frequency components, so that the receiver can extract the clock synchronous information from the code stream, clock synchronization information receiving end can be guaranteed with the correct timing from the received the raw data signal is reproduced. [0003] 4B5B coding is used, the input 4-bit data is converted to the output 5. Typically using a lookup code table designed to complete the work of the encoding and decoding, thus the transmission and reception ends require additional memory to store the code table. 4B5B coding may also reduce the quality of encoding, i.e., the same logic value excessive number of successive bits, for example 8-bit data by using the 4B5B code transmission. En...
