Abstract
The present invention relates to a mobile terminal and a method for the data sending between the television functional module of the terminal and the mobile functional module. At least one working state output port is arranged on the television functional module and the mobile functional module of the terminal, to output the self working state; at least one working state input port connected with the working state output port is arranged on the television functional module and the mobile functional module, to get the working state of the working state output port. The method comprises the following steps that the working state of a module for receiving data is got firstly before a module needing to send data in the television functional module and the mobile functional module sends data, and before the working state of the module for receiving data does not need to be waken up, the module directly sends data, otherwise sending data after the module for receiving data is waken up. The present invention effectively improves the efficiency of the serial port communication.
Description
Technical field
The present invention relates to a kind of portable terminal and TV functions module thereof and locomotive function intermodule and send data method, relate in particular to a kind of method of these two intermodules transmission data of TV functions module and locomotive function module of the mobile phone that TV functions arranged.
Background technology
Along with the development of technology, the mobile TV function is more and more paid attention to by each big operator, and the mobile phone terminal that has the mobile TV function also begins to develop thereupon.Generally speaking, base band and radio-frequency module (being called the locomotive function module in this patent) that TV in the mobile phone is accepted the base band of module and radio frequency part (being called the TV functions module in this patent) and mobile phone are two independent parts, and both handle the signal of each autocorrelative audio frequency and video etc. respectively.Real-time information interaction can take place between this two parts module (locomotive function module and TV functions module), as confirm the other side's operating state and for the preemption information of physical hardware resources etc., and the mode that this information interaction adopts usually is to realize by serial ports.Following problems may be encountered and when realizing information interaction by serial ports: when mobile phone is in holding state, the TV functions module is issued the information of mobile module and can be lost, this is because mobile module uses for power saving when standby is the unusual clock of low frequency (as 32kHz) with respect to operating state, is the data that can not detect and respond the serial ports transmission in real time in this case.Existing solution is before sending data, wake the relevant portion of locomotive function module up by the interruption controls signal, make it operating state and switched to by standby mode under master clock (as the 13MHz) pattern of high frequency, the locomotive function module can correctly detect and accept the data of serial ports transmission under the master clock pattern.Equally, when the TV functions module was in holding state, the locomotive function module was issued the information of TV functions module and also can be lost.This is because the TV functions module before being not activated, also only is the low-frequency clock operating state that is under the holding state, is the data that can not detect and respond the serial ports transmission in real time in this case.Existing solution is before sending data, wake the TV functions module up by the control interrupt signal, make it operating state and switched under the master clock pattern by standby mode, the TV functions module can correctly detect and receive the data of serial ports transmission under the master clock pattern.
Figure 1 shows that the TV functions module and the locomotive function module serial communication control circuit schematic diagram of existing Digital Video Broadcasting Handheld.When the TV functions module needs toward locomotive function module transmission data, at first the transmission pin of the interrupt signal IRQM that mails to the locomotive function module (Interrupt Signals ToMobile Function Module) by the TV functions module produces an interrupt signal, and the IRQM that mails to the locomotive function module receives pin, after the locomotive function module receives IRQM interrupt signal from the TV functions module, in interrupt handling routine, operating state switched to the master clock pattern, and under the master clock pattern, carry out the serial data communication with the TV functions module.
When the locomotive function module needs toward TV functions module transmission data, at first send pin and produce an interrupt signal by the interrupt signal IRQT (Interrupt Signals to TV Function Module) that mails to the TV functions module, and the IRQT that mails to the TV functions module receives pin, after the TV functions module receives IRQT interrupt signal from the locomotive function module, operating state with mobile phone in interrupt handling routine switches to the master clock pattern, and carries out the serial data communication with the locomotive function module under the master clock pattern.
The shortcoming that shows of said method is in actual use: can't obtain the other side's current working state before sending data, therefore no matter whether the other side is under standby mode, for correct transceive data, before sending data, all need to wake up the other side's operation by interrupt signal.Interrupt the operation that wakes up before the data again if not under standby mode, send the other side at this moment, can reduce the efficient of serial communication.
