Input interface managed on mobile phone side

To realize the structure in which different systems run on two microprocessors, both of the microprocessors have main memory. Also, Fujitsu ensured that peripheral devices can basically be accessed by only one system so that two systems do not compete with each other. It seems that the system on the OMAP (Symbian) manages peripheral devices except for those that can only be used in the Windows 7 Mode (such as wireless LAN, HDMI and USB host Note 1)).

Note 1) Fujitsu developed a "cradle set," which will be separately sold, for the F-07C. It can be used as a charging stand and has four UBS ports and an HDMI output port. The F-07C does not have any HDMI output port or USB host port.

For example, even in the Windows 7 Mode, user inputs via the touch panel, keypad, etc are detected by Symbian on the OMAP side and sent to Windows 7. Incoming calls to the mobile phone are also managed by Symbian. When the F-07C receives a call, it automatically switches the Windows 7 Mode to the Mobile Mode.

Data can be exchanged between the two systems by sharing an SD memory card.

"As the integration of the two systems proceeds, they become more complicated," said Nobuo Otani, executive director of Fujitsu. "We limited the integration to data sharing. And, as a result, we succeeded in developing clear-cut systems."
