Integrated circuit and method of storing probability tables for video decoding
An integrated circuit is provided. The integrated circuit includes a first volatile memory, a second volatile memory, and a video decoder. In response to the video decoder starting video decoding on a current frame of a video stream, the video decoder reads an initial probability table for the current frame from a memory unit external to the integrated circuit, and stores the initial probability table in the first volatile memory. When a decoding phase of the current tile is completed, the video decoder complements the probability table corresponding to each row of the second volatile memory according to control flags corresponding to the rows of the first volatile memory and the second volatile memory to obtain a complete probability table, and writes the complete probability table to the memory unit.
