Abstract
PURPOSE: To make it possible to attain access to an external information code at a high speed by making size comparisons by setting up a reference code table which branches off on the tournament system with a number of digits equal to that of external information code.
CONSTITUTION: In memory 13, Chinese-character codes, for example, are arrayed according to size and in a toothless state and in memory 14, character pattern codes are stored. Memories 13 and 14 are controlled by address counter 12; and codes in memory 13 are compared with an external information code by code size deciding circuit 15 and when identity is found, output gate 16 of memory 14 is opened to read character pattern codes in memory 14. Circuit 15 sets the reference code for the tournament system and makes a size decision by comparing a four-bit external code, for example, to medium value "1000" firstly to branch off. Further, it is compared to the medium value of a branch destination according to the tournament system to make the size decision until identity is obtained finally. Consequently, access to the external code can be attained more rapidly than before.
