Abstract :
Constant grade compression is a new compression method. But the speed of this method is too slowly. How to compute base-data is an important question in constant grade compression. The optimization on base-data computing is studied and the computing speed is advanced in this paper. Firstly, the theory of constant grade compression method is expatiated. Then, the factorial method and proportion method is advanced to compute based-data. Some relative formulas are educed. The consume time of three different computing methods is compared. At last, it is found that proportion method has more preponderance to compute base-data. Proportion method advances much speed on computing base-data efficiently. Further, the efficiency of constant grade compression technology is advanced. All these make constant grade compression technology go ahead quickly to utility.
