<p><P>PROBLEM TO BE SOLVED: To realize Exp-Golomb coding, required for coding a syntax element in H. 264/AVC, at high speed with a small-scale integrated circuit. <P>SOLUTION: When the data length of an Exp-Golomb coded data does not exceed a bus bit length, the entire coded data are output to the bus at one time. When the data length of the coded data exceeds (2×K-1) times as long as the bus bit length while it does not exceed 2×K times, a first portion is output to the bus after being divided into one or a plurality of times, and a second portion and a third portion are output to the bus after divided into one or a plurality of times. When the data length of the coded data exceeds 2×K times as long as the bus bit length while it does not exceed (2×K+1) times, the first portion is output to the bus after being divided into one or a plurality of times, and a first data not exceeding the bus width, a second data and a third data exceeding an integer multiple of the bus width are output, and the third portion is output to the bus after divided into one or a plurality of times. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
