When wishing that AP module or CDMA module enter battery saving mode work, can adopt sleep-awake mechanism of the present invention to finish this function.The AP module to the waking up/the sleep state inquiry of AP module, all adopts general serial I/O (GPIO, General Purpose I/O) interface mode to finish CDMA module and CDMA module.
Fig. 1 is AP module and CDMA GPIO interface signal line connection diagram among the present invention, shown in figure l, adopts eight control/status poll interface lines between AP module and the CDMA module, and the functional description of the every root interface line of GPIO interface is as follows:
1, CDMA module switch control line (CDMA_ON_KEY) is used for the AP module CDMA module is carried out ON/OFF control;
2, the unusual control line of CDMA module (CDMA_ABNORM_CTRL) is used for the AP module and sends reset signal to CDMA;
3, CDMA module status line (CDMA_STATUS) is used for the operating state that the AP module is inquired about the CDMA module;
4, the PXA processor wakes CDMA module (PXA_WAKEUP_CDMA/PXA_IRQ) up, is used for the AP module and wakes the CDMA module up;
5, (CDMA_IRQ) interrupted in the request of CDMA module, is used for the CDMA module and wakes the AP module up;
6, PXA processor ready (PXA_READY), this signal has two kinds of functions: the one, when being used for the sleep of AP module,, need to prove that this GPIO interface does not have arousal function by interrupting Request Notices CDMA module; Another function is the sleep state that is used for CDMA module inquiry AP module.
7, CDMA module ready (CDMA_READY), this signal has two kinds of functions: the one, by interrupting Request Notices AP module, need to prove that this GPIO interface does not have arousal function when being used for the sleep of CDMA module; Another function is the sleep state of AP module inquiry CDMA module.
8, usb host end ready (USB_HOST_READY) is used for setting up the back notice CDMA module that finishes at the USB interface communication link of AP module.
AP module and CDMA module are carried out the signal sequence schematic diagram of sleep-awake operation among Fig. 2 the present invention, and as shown in Figure 2, the specific implementation process of the sleep-awake mechanism of AP module and CDMA module is:
Step 201, CDMA module and AP module are when waking attitude up, CDMA module and AP module operate as normal;
At this moment, the PXA_WAKEUP_CDMA line is a low level, and CDMA_IRQ is a low level, is high level on PXA_READY, CDMA_READY, the USB_HOST_READY line.At this moment, the Host of USB interface end and Client end all are in operating state, can carry out data between AP module and the CDMA module at any time and transmit.
Step 202: when CDMA module end-of-job, when no longer including other operations, the CDMA module enters sleep state, is in energy-saving mode;
Be specially: CDMA_READY is changed to low level by the high level of operating state, produce a trailing edge interrupt notification AP module, the ready USB_HOST_READY of usb host end responds this trailing edge and interrupts, and becomes low level subsequently, and promptly the CDMA module enters sleep state; At this moment, USB interface is closed, and the AP module will detect a USB device and extract incident.
Step 203: after the CDMA module enters sleep state, when not having new operation to be performed in AP module a period of time, PXA_READY is changed to low level from original high level, produces a trailing edge interrupt notification CDMA module, this moment, the AP module also entered sleep state, promptly entered energy-saving mode.Described AP module enters and dormantly is system default during this period of time or sets by terminal that for example, can be set to: AP module backlight kept lighting up as 20 seconds.If the AP module is not received new operation requests in these 20 seconds, then the AP module is just closed backlight after 20 seconds, enters sleep state.
During the sleep of AP module, by PXA_READY interrupt notification CDMA module.PXA_READY is in high level state under the normal condition, when the AP module need be slept, the PXA_READY signal is put low level, and produce a trailing edge interrupt notification CDMA module, at this moment, the AP module will be closed the Host controller of USB interface, thereby the Host end is connected from disconnecting in logic with the AP module.
Step 204: when the AP module had new action need to carry out or receives the request of CDMA module, the PXA_READY holding wire produced a high level, became high level by the low level of original sleep state, and this moment, the AP module was waken up, and prepared to enter operating state.
When the AP module is waken up,, PXA_READY is put high level, produce an interrupt notification CDMA module by PXA_READY interrupt notification CDMA module.After the AP module is waken up, if there are data to send, the AP module will reopen the Host controller of USB interface.
Step 205: when the CDMA module will send data or the AP module need be when the CDMA module sends instruction or data to the AP module, the AP module sends a positive pulse signal by PXA_WAKEUP_CDMA/PXA_IRQ to the CDMA module, afterwards the CDMA_READY signal is drawn high from low level and be high level, after CDMA_READY signal high level continues for some time USB_HOST_READY is changed to high level, finish the wakeup process of CDMA module, can enter operate as normal after the CDMA module is waken up.
In the process that the CDMA module is waken up, when the PXA processor sends interrupt instruction by the PXA_WAKEUP_CDMA signal to the CDMA module, be that the CDMA module is when receiving the pulse signal of PXA_WAKEUP_CDMA, the Host end of AP module USB interface begins to enter initialization procedure simultaneously with the Client end of the USB interface of CDMA module, when the Client of CDMA module end is finished the initialization set-up procedure earlier, the CDMA_READY signal is put high level, when the Host of AP module end is finished the initialization preparation by the time, the AP module is changed to high level with USB_HOST_READY, and synchronous communication links foundation is finished between the Host of this USB interface end and the Client end at this moment.
Because the time before the Host of USB interface end is started working is longer than the Client end.Interior during this period of time link instability should not communicate.Therefore, both sides all are provided with buffering area mechanism, synchronization link do not set up during this period of time in, if there are data to send, place it in earlier in the buffering area, treat that the USB interface communication link is set up to send again after finishing.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
