Title:
MBNB CODE CONVERSION SYSTEM
Document Type and Number:
Japanese Patent JPH01314021
Kind Code:
A
Abstract:
PURPOSE: To simplify the hardware constitution by devising all conversion codes in 2 kinds of n-bit to be same code or complementary codes in an mBnB code conversion table (m, n are natural numbers, n>m).
CONSTITUTION: The conversion codes of states 1, 2 in the mBnB code conversion table are devised to be same codes or complementary codes mutually. Thus, the n-bit conversion code in the states 1, 2 is the same as the other conversion code as it is or by inverting one conversion code. Thus, it is not required to provide two kinds of memory areas corresponding to the conversion codes of the states 1, 2 and it is not required to switch the 2 kinds of the conversion codes in response to the states.
