Abstract
A signal select control circuit for a select circuit, which selects one of a plurality of predetermined signals, in accordance with a select signal comprising an arrangement change circuit, a priority-based select circuit, and an arrangement reverse circuit. The arrangement change circuit receives n input signals (n is an integer) arranged in parallel in accordance with a first arrangement and changes an arrangement of the n input signals in accordance with a control signal indicative of a priority order so that the n input signals are arranged in parallel in accordance with a second arrangement based on the priority order. The priority-based select circuit receives the n input signals having the second arrangement and generates n output signals arranged in parallel in accordance with a third fixed arrangement. The n output signals indicates one of the n input signals, which has a highest priority among valid input signals among the n input signals. The arrangement reverse circuit changes an arrangement of the n output signals so that the n output signals are arranged in parallel in accordance with an arrangement identical to the first arrangement of the n input signals. The n output signals arranged in parallel in accordance with the arrangement identical to the first arrangement serve as the select signal.
