Embodiment Construction

[0042] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0043] According to an embodiment of the present disclosure, an encoding method is provided, such as figure 1 As shown, the method may include the following steps S101 to S103.

[0044] In step S101, read the Nth frame data to be encoded;

[0045] In step S102, perform a first operation on the Nth frame data, and output a first operation result;

[0046] In step S103, during the period of performing the first calculation on the Nth frame data, a second calculation is performed based on the first calculation result output from the first calculation on the N-1th frame data, and the second calculation is output As a result, N is a positive integer.

Abstract

The invention relates to a coding method and device and relates to the technical field of electronics. According to the method and the device, the coding processing capability of a coder can be improved. The method comprises the steps of reading to-be-coded Nth frame data; carrying out first operation on the Nth data and outputting a first operation result; and in the period of carrying out first operation on the Nth frame data, carrying out second operation based on a first operation result which is output by carrying out the fist operation on N-1th frame data, and outputting a second operation result, wherein the N is a positive integer.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to the field of encoding technology, and in particular, to an encoding method and device. Background technique [0002] At present, when encoding, it is first necessary to read the Nth frame of data to be encoded, then write the read Nth frame of data into the output data memory and use the encoding matrix to calculate the Nth frame of data to obtain the check digit. After the check code calculation of the Nth frame data is completed, read the N+1th frame data, and then write the read N+1th frame data into the output data memory and use the encoding matrix to encode the N+1th frame The data is calculated to obtain the check digit, and so on, until the calculation of all the check digits is completed. [0003] Assuming that it takes 520 clock cycles to write one frame of data into the output data memory, and 560 clock cycles to calculate the parity bit, it takes a total...
