Abstract
PURPOSE:To perform level conversion by using a no-code operator, by converting reference level data according to conversion level data. CONSTITUTION:Data to be level-converted is denoted as S, reference level data as P, and conversion-level data as G. Then, data after conversion is expressed by (1) (where each signal consists of eight bits). This is modified to obtain expressions (2) and (3). For this purpose, converted data S is multiplied by conversion data G by multiplier 11 to perform the arithmetic of the 1st term of expression (2). Next, bit converter 12 that converts reference data P according to conversion data G converts conversion data G to perform the arithmetic of the 2nd term of expression (3). Then, this output and the output of multiplier 11 are added together by no-code adder 13. Thus, the level conversion can be attained by using the no-code operator.
