PROBLEM TO BE SOLVED: To attain signal communication between modules in a transmission system whose transmission energy is different for each channel by minimizing energy consumption related with signal communication. SOLUTION: A resource register 28 transmits a using situation signal (1: non-use, 0: use) in which the using situation of each channel is expressed with one bit per channel, and in which each bit from an MSB(most significant bit) to an LSB(least significant bit) is successively assigned to the channels from the channel whose amplitude is smaller to the channel whose amplitude is larger to a channel selecting part 30. The channel selecting part 30 selects the channel corresponding to the bit which is the closest to the MSB from among the bits whose values of the using situation signal are '1' as a transmission channel, and selects the channel whose amplitude is smallest from among the non-use channels, and transmits the channel number to a channel assigning part 26. The channel assigning part 26 assigns the channel number from the channel selecting part 30 to a module number from a module selecting part 24, and outputs it as an arbitrated result. |
