Abstract

The application provides a sideband compensation acceleration method, an acceleration device, a computing device and a storage medium. The sideband compensation acceleration method comprises the following steps: obtaining sideband data; adaptively setting a candidate concurrency parameter and determining an optimal concurrency parameter P; dividing the sideband data into a plurality of vectors according to the determined optimal concurrency parameter P; performing parallelization calculation on each divided vector and judging whether each vector matches; and updating the sideband data according to the matching state of the plurality of vectors. Through the sideband compensation acceleration method of the application, sideband compensation data can be calculated in parallel based on an adaptive compensation algorithm, and the coding efficiency is improved.
