Communication system, master device and slave device, and communication method, configured to handle plural concurrent requests
Abstract:
A communication system includes a master device and slave devices. Each slave device includes a request signal generation part configured to, when data to transmit is generated, generate a request signal indicating a transmission request to a master device; and a transmission part configured to transmit the request signal to the master device. The master device includes a request signal reception part configured to receive the request signals from the slave devices; a selection part acting configured to select one of the slave devices according to the request signals received by the reception part; a transmission part configured to transmit a signal indicating to allow data transmission to the slave device selected by the selection part; and a data reception part configured to receive data from the selected slave device.
