Embodiment Construction

[0020] The invention will be further described below in conjunction with specific embodiments.

[0021] The input signals of the high-speed 8B / 10B encoder include 32-bit input data Din[31:0], input disparity Dispin, and input data special coding indication signals k1, k2, k3, and k4. The 32-bit input data Din[31:0] is divided into four 8-bit data, which are respectively input to four high-speed 8B / 10B encoding devices. The output signal of the high-speed 8B / 10B encoder has 40-bit output data Dout[39:0] and output disparity Dispout. The 40-bit output data Dout[39:0] is composed of 10-bit output data of four 8B10B units. In this way, each 8B10B unit has 8-bit input data of this module (Din[7:0], Din[15:8], Din[23:16] or Din[31:24]), and the input is not equal (Dispin, Disp1, Disp2 or Disp3), input data special coding indicator signal (k1, k2, k3 or k4), and 10-bit output data (Dout[9:0], Dout[19:10], Dout[29 :20] or Dout[39:30]). Between adjacent modules, processing higher-o...

Abstract

The invention relates to a high-speed 8B/10B encoding device which is characterized by comprising a special signal determining module, a 5B/6B lookup table, a 5B/6B operating sign, a 3B/4B lookup table, a 3B/4B operating character, a special character coder and an output producing module. According to the high-speed 8B/10B encoding device, a basic lookup table can be constructed and operations of lookup table results can be previously ensured so as to quickly achieve a high-speed coder on the base that a designer needs not to deep understand an 8B/10B encoding principle.

Description

technical field [0001] The invention relates to the communication field, in particular to a high-speed 8B / 10B encoding device and an encoder. Background technique [0002] In many high-speed serial interfaces currently used, data encoding often adopts 8B10B encoding. 8B10B encoding is used in the SuperSpeed ​​mode stipulated in USB3.0. The 8B10B encoding literally converts 8-bit data into 10-bit data for transmission. The purpose of encoding data is to avoid excessive continuous "1" and "0" and ensure DC balance. [0003] However, the principles of existing encoding devices are complex, and developers need to spend a lot of time designing high-speed encoders without prior knowledge of the principles and implementation methods of the algorithms. Contents of the invention [0004] The technical problem solved by the invention is to provide a high-speed 8B / 10B encoding device and encoder which are modularized and easy for users to design. [0005] In order to achieve the ...
