Abstract:
1. A communication device which communicates with a target communication device, comprising: a communication controller; a general-purpose processing unit configured to communicate with the target communication device via the communication controller; a data transfer processing unit configured to receive data from the target communication device via the communication controller; and a starting unit configured to start up the data transfer processing unit, wherein the general-purpose processing unit receives a data transfer start request from the target communication device, the starting unit starts up the data transfer processing unit when the general-purpose processing unit receives the data transfer start request, the general-purpose processing unit or the data transfer processing unit notifies a data transfer start response to the target communication device after the data transfer processing unit is started up, the communication device, further comprises: upon receiving the interrupt signal from the communication controller, the data transfer processing unit processes the interrupt signal when the interrupt signal is a predetermined interrupt signal, and outputs a first interrupt signal to the general-purpose processing unit when the interrupt signal is other than the predetermined interrupt signal, and the general-purpose processing unit includes a general-purpose driver unit configured to process the interrupt signal from the communication controller, and a proxy driver processing unit configured to process the first interrupt signal input from the data transfer processing unit.
