1. the method for a parallelly processing at least two binary values, it is used in the electronic installation, and the binary value string is carried out arithmetic coding, and said method comprises:

  • Utilize present scope to calculate the scope of first binary value in the above-mentioned binary value string;

    When above-mentioned first binary value is most possible symbol, utilize above-mentioned present scope while forward direction to estimate a plurality of possible scope and the floor value of second binary value in the above-mentioned binary value string;

    AndWhen the scope of above-mentioned first binary value calculates, utilize scope that aforementioned calculation goes out from above-mentioned a plurality of possible scopes and floor value, to select the range of results of above-mentioned second binary value.
