PROBLEM TO BE SOLVED: To provide an arbitration circuit capable of reducing the occurrence of buffer overflows in the entire arbitration circuit, even when a plurality of buffers high in probability of overflows are present, in an arbitration circuit using a plurality of buffers. SOLUTION: A buffer 91 retains input information input from an upper device. An input information amount detection means 92 detects an input information amount retained in the buffer 91 when input information is input. A priority determination means 93 compares the input information amounts on a buffer 91 basis detected by the input information detection means 92 to determine output priority being priority of the buffer 91 for causing the input information to be output. An output instruction means 94 causes the input information retained in the buffer high in the output priority to be output. COPYRIGHT: (C)2011,JPO&INPIT
