US 8,476,924 B2 · Majority decision circuit

Abstract

A majority decision circuit includes: a majority decision unit configured to compare first data with second data to decide whether one of the first data and the second data has more bits with a first logical value; and an offset application unit configured to control the majority decision unit so that the majority decision unit decides, in a case when the number of bits with the first logical value among the first data is equal to the number of bits with the first logical value among the second data, that the first data have more bits with the first logical value if offset is a first setting value in a first phase and decides that the second data have more bits with the first logical value if the offset is a second setting value in a second phase.

A majority decision circuit, comprising:

a majority decision unit configured to compare first data with second data to decide whether one of the first data and the second data has more bits with a first logical value;
and
an offset application unit configured to control the majority decision unit so that the majority decision unit decides, in a case when the number of bits with the first logical value among the first data is equal to the number of bits with the first logical value among the second data, that the first data have more bits with the first logical value if offset is a first setting value in a first phase and decides that the second data have more bits with the first logical value if the offset is a second setting value in a second phase.

A majority decision circuit, comprising:

a first majority decision unit configured to compare first data with second data to output decision results on whether one of the first data and the second data has more bits with a first logical value and output a logical value when the number of bits with the first logical value among the first data is equal to the number of bits with the first logical value among the second data;
a second majority decision unit configured to compare first data with second data to output decision results on whether one of the first data and the second data has more bits with a first logical value and output a logical value that is an inverse of the logical value output from the first majority decision unit when the number of bits with the first logical value among the first data is equal to the number of bits with the first logical value among the second data;
and
an equal signal generator configured to activate an equal signal representing that the number of bits with the first logical value among the first data is equal to the number of bits with the first logical value among the second data when the logical value output from the first majority decision unit is different from the logical value output from the second majority decision unit.
