PURPOSE:To simplify the constitution of a majority circuit by adding the input data on plural bits received repetitively in plural times to sore the results of the additions and deciding the majority value based on these stored results of additions. CONSTITUTION:The head one of input data Di on plural bits received repetitively in plural times is stored in a memory circuit 2 via a selection circuit 3. This stored head data is added with the next input data for each bit via an addition circuit 1 and the results of these additions are stored in the circuit 2. Hereafter the addition operations are repeated for each data and the number of logics '1' are counted for each bit and stored in the circuit 2. Based on the results of additions, the majority value of each bit is outputted from an output circuit 4 as the output data D0. Thus it is possible to obtain a majority circuit of a simple constitution that can perform the majority processing without storing all input data. |
