VIDEO DECODING METHOD AND DEVICE THEREOF

摘要

Embodiments of the present application provide a video decoding method and a device thereof, which improve the accuracy of data processing while simplifying a micro-architecture design of inverse discrete cosine transform during the video decoding process. The method comprises: sequentially storing received to-be-decoded data in multiple first data registers and multiple second data registers that are separated from one another; performing shifting and table lookup processing on the to-be-decoded data stored in the first data registers and the second data registers, so as to respectively obtain a table lookup result corresponding to a first coefficient matrix and a table lookup result corresponding to a second coefficient matrix; and performing distributed computing on the table lookup result corresponding to the first coefficient matrix and the table lookup result corresponding to the second coefficient matrix, so as to obtain decoded data.
