Abstract

PURPOSE: To ensure a high-speed detection of the discontinuous data of large capacity by arranging the codes of binary 4 bits possessed by many address form small to large value in sequence and then detecting the scale relations with narrowing the range of the address.
CONSTITUTION: In the case of the addresses from 0 to 6, the addresses from B0 to Bn can exist in general. First, the codes composed of binary 4 bits are arranged from small to large value covering the addresses from 0 to 6, thus producing the chart as shown. Secondly, (0 + 6th address)/2 = 3 is obtained when code 0010 is retrieved. And thirdly, the ternary 3 is used as the address to read out the corresponding code, thus obtaining decimal code 5 with 0101. After this, the scale relations of those addresses are compared as the 4th means, and then (0 + 3)/2 = 1.5 is obtained based on 0010<0101 as the 5th means, thus calculating about 1.
