Abstract: Disclosed herein is a method of performing an arithmetic coding for data symbols, comprising: creating an interval for each of the data symbols, the interval being represented based on a starting point and a length of the interval; updating the interval for each of the data symbols; checking whether the updated interval is included in a specific range; and renormalizing the updated interval based on a result of the checking.

Abstract: Disclosed herein is a method of performing an arithmetic decoding for data symbols, comprising: creating a decoding table index; obtaining an upper bound value and a lower bound value of a ratio between an interval length and a point within an interval assigned to a symbol from a ROM table; obtaining initial values for a bisection search from a RAM table based on the upper bound value and the lower bound value; and searching a value of sequence in the interval, wherein the interval is determined based on the initial values.
