Disclosed is a method for performing arithmetic decoding on a data symbol, the method comprising the steps of: generating a decoding table index; obtaining, from an ROM table, upper and lower boundary values for the ratio between a point in a section, which is assigned to a symbol, and the length of the section; obtaining an initial value for a bisection search from an RAM table on the basis of the upper and lower boundary values; and searching for a sequence value in the section, wherein the section is determined based on the initial value. |
