Embodiment Construction

[0047] In order to enable those skilled in the art to better understand the present invention, the parallel BCH encoding circuit provided by the present invention will be specifically described below in conjunction with specific embodiments, figure 2 is a structural schematic diagram of the parallel BCH encoding circuit.

[0048] In the parallel BCH encoding circuit provided by the present invention, it includes: M arithmetic unit (pipeline cell) circuits S210, one feedback unit (feedback cell) circuit S220 and one data output unit (dataout cell) circuit S230, wherein, M = m L , m is the number of bits of the check code, and L is the degree of parallelism.

[0049] The operation unit circuit S210 is used to complete the function of the BCH code generation matrix. The encoding process essentially uses the information code to calculate the check code according to the generation matrix, so the operation unit circuit S210 is t...

Abstract

A circuit used on parallel BCH coding is prepared as serial-connecting multiple operation circuit, feedback unit circuit and data output unit circuit as well as utilizing flow line mode to carry out BCH coding on input-parallel data for making said circuit have great generality.

Description

technical field [0001] The invention relates to the technical field of error correction coding for data, in particular to a parallel BCH coding circuit, coder and device. Background technique [0002] The BCH code is a kind of error correction code, which is mainly used in the error control of the digital system. BCH codes have very important applications in data transmission processes such as communication, storage, and information transfer. There are two ways to BCH encode data, one is serial encoding, and the other is parallel encoding. [0003] figure 1 The structure of the serial BCH encoding circuit is shown. The structure of the serial BCH encoding circuit is relatively simple, and the input / output data of the circuit are all in a serial manner. Among them, g i (i=1, 2, . . . , n-k-1) are preset parameters, and D represents a register. When BCH encoding is performed on data in a serial manner, if k bits of data need to be BCH encoded and the check code is m bits...
