Abstract:
1. A wireless communication system for updating logic-circuit data for implementing a logic circuit in a variable logic circuit unit, the wireless communication system comprising: a transmission source device configured to transmit logic circuit update data by wireless communication; at least one transmitting device configured to receive the logic-circuit update data from the transmission source device by wireless communication; and a transmission destination device that includes the variable logic circuit unit, wherein the transmission destination device is configured to receive logic-circuit update data, and updates existing logic-circuit data of the variable logic circuit unit with received logic-circuit update data, wherein the transmission source device is further configured to transmit a test signal to the transmitting device and the transmission destination device by wireless communication, the transmitting device and the transmission destination device, upon receiving the test signal, add to the test signal an identification number thereof and a receiving time of the test signal to obtain a data-added test signal, and are further configured to transmit the data-added test signal by wireless communication, and the transmission source device is further configured to receive the data-added test signal by wireless communication from any of the transmitting device and the transmission destination device, is further configured to determine a communication route between the transmission source device and the transmission destination device via the transmitting device with a shortest communication time from among potential communication routes based on the identification number and the receiving time of each of the transmission destination device and the transmitting device obtained from received data-added test signal, and is further configured to transmit the logic-circuit update data so that the logic-circuit update data is sent to the transmission destination device via the communication route, and wherein the transmission source device is further configured to: each of the transmitting devices, upon receiving the logic-circuit update data, is configured to:
