Communication device with fast start mode for transfering data to temporary areas beyond file system control

摘要

According to one embodiment, a communication device includes a data storage device and following units. The reception unit receives data from another communication device. The data storage device includes a data area controlled by a file system and a temporary area beyond control of the file system. The processing unit operates in one of first and second start modes, the processing unit being started faster in the second start mode than in the first start mode. The processing unit operating in the second start mode writes the received data to the temporary area, copies the received data in the temporary area to the data area after completion of data reception, and erases the received data in the temporary area after copying.

1. A communication device comprising:
a reception unit configured to receive data from another communication device; a data storage device including a data area controlled by a file system and a temporary area which is beyond control of the file system, the temporary area being allocated a fixed logical address; and a processing unit configured to operate in one of a first start mode and a second start mode to write the received data to the data storage device, the first start mode being a mode in which the processing unit operates according to a start request generated at the communication device, the second start mode being a mode in which the processing unit operates according to a start request provided from outside of the communication device, the processing unit having a startup time that is shorter in the second start mode than in the first start mode, wherein if the processing unit operates in the second start mode, the processing unit writes the received data to the temporary area, copies the received data in the temporary area to the data area after completion of data reception, and erases the received data in the temporary area after copying.
