Problems solved by technology

Through theoretical derivation, we found that by analyzing the data flow The theoretical upper limit of saving transmission time at the same clock frequency after base conversion is about 36.907%. Obviously, the existing methods and technologies are far from reaching this value, and there is still a lot of room for improvement

Embodiment Construction

[0096] The specific ternary level mentioned in the present invention can add another -V on the basis of the usual binary +V and 0. In this way, the increase of the bit error rate can be avoided by increasing the level of a V / 2, because the potential difference between different bits is not reduced.

[0097] The specific implementation manners of other parts of the present invention have been described in detail in parts 1-9 of the summary of the invention.

[0098] The present invention considers the requirement of hardware scale in different application occasions and preferably proposes the conversion format with 11b7t and 19b12t However, according to the elaboration and derivation in the content of the invention 1 of the present invention, it can be known that the efficient conversion format is not limited to these two, and there are many other options in the case of ignoring the hardware scale. Therefore, the present invention is not limited to the two conversion formats ...

Abstract

The invention relates to two types of wired communication methods and systems for occasions with different requirements. The two systems both comprise two parts of physical conversion modules, one part is used for converting binary data flow into ternary data flow for transmitting, and the other part is used for reducing the received ternary data flow into the binary data flow. The two systems carry out the conversion between the binary data flow and the ternary data flow by adopting two conversion formats of 11b7t and 19b12t respectively, respectively save 36.4% and 36.8% of transmission time under equivalent clock rate, and meet the requirements of the occasions with different application requirements on hardware scale. The conversion operations can be carried out through the steps with binary code, 21BCT (Binary Coded Ternary) code, and ternary code. In the conversion step, the conversion link of binary code and the 21BCT code can be implemented through the mode of storage address mapping, , therefore, the method ensures that the hardware circuit is simplified.

Description

technical field [0001] The invention relates to high-speed wired communication, and in particular relates to a method and a system for replacing binary data flow with ternary data flow to improve wire transmission efficiency. Background technique [0002] The usual wired communication methods generally use binary transmission, but theoretically the efficiency of ternary communication is optimal. In order to be compatible with binary computer systems, a The abstraction layer for binary conversion is used to convert between binary data streams and ternary data streams. [0003] So, how exactly What about conversions? Generally, every n-bit binary bit (bit) in the binary data stream is converted into m-bit ternary bit (trit) for conversion, which is called nbmt. In the existing n-m value method, the 100Base4T specification of 100M Ethernet adopts the 8b6t conversion format, which is to convert 8 binary bits into 6 ternary bits. This method is compared with the traditional...
