Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is the flow chart of an application interface display packing in embodiment.As shown in Figure 1, the method comprises:
S10: create Circular buffer, interface display application and interface display data that constantly buffer memory application is submitted to.
Set Top Box is when showing application interface, and application can be submitted interface display application and interface display data to Set Top Box.Operation is originally, application call drives the UpdateScreen operation of layer, UpdateScreen operation receives in the mode of serial interface display application and the interface display data that application is submitted to, be that UpdateScreen operational correspondence will receive and carry out with each interface display application of submitting to, the interface display data that each interface display application is corresponding show, application interface display is upgraded.Because the time that once needs to take 50ms left and right is carried out in UpdateScreen operation, if be applied in UpdateScreen operation implementation, in 50ms, submit a plurality of interface display applications to, the interface display application of submitting to afterwards just need to be waited in line, and after UpdateScreen operation by the time executes once, carries out the interface display application of queuing up below again.For example, application A has proposed a, b, tri-interface display applications of c in 50ms, and first now UpdateScreen operation carries out a, and b and c just need to wait for, UpdateScreen operation by the time executes after a, then carries out b, executes the last c of execution after b.Because UpdateScreen operation each time all will take 50ms, between this, application may have been submitted a lot of interface display applications to, especially in the situation of multithreading application, the program of waiting in line so shows that application will be a lot, need to wait for just can be performed for a long time, this will cause serious card to pause.
In this embodiment, be pre-created a Circular buffer, Circular buffer constantly receives interface display application and the interface display data that application is submitted to, and carries out circular buffer, and interface display application and interface display data that application is submitted to are carried out transfer.All interface display applications of submitting to of application and data all can first be submitted to carries out buffer memory in Circular buffer, but not directly drive layer call UpdateScreen operation.Can efficient circulation store a plurality of programs demonstration applications and data like this, when a plurality of threads application while submit applications, only can increase the interface display application record number in Circular buffer, not take the operating time of demonstration.
In further execution mode, Circular buffer comprises a write pointer, read pointer and data buffer area.Write pointer and read index and be used for respectively controlling writing and reading of data buffer area.When write pointer or read pointer move to end, data buffer area, all can automatically get back to the beginning of data buffer area, circulate.Data buffer area has predetermined space, can a plurality of interface display applications of buffer memory and interface display data.
Create after Circular buffer, application or driving layer can be write read operation by an access Circular buffer.If have a plurality of write operations or read operation, access Circular buffer simultaneously, will exist a plurality of write operations or read operation to operate the situation of a slice data buffer area simultaneously, this will affect the correctness of data buffer zone data, especially in the situation that multithreading is applied.For avoiding this data exception situation to occur, guarantee the correctness of data, step S10 also comprises: create mutual exclusion lock, mutual exclusion lock only allows a write operation or read operation to operate Circular buffer district at every turn, and to Circular buffer, district protects.Concrete, be applied in while writing interface display application and data to Circular buffer district, first obtain mutual exclusion lock, obtain the authority that writes to Circular buffer, mutual exclusion lock only allows the application that obtains mutual exclusion lock to write Circular buffer, and other application can not write, and discharges immediately mutual exclusion lock after writing.When applying or drive layer to read Circular buffer, also need first to obtain mutual exclusion lock, obtain the authority that reads to Circular buffer, after reading, discharge immediately mutual exclusion lock.By creating mutual exclusion lock, the read operation of Circular buffer is limited, only allow an application to conduct interviews to Circular buffer at every turn, thereby guaranteed the correctness of the data in Circular buffer district.
S20: monitor in real time the interface display application of buffer memory in Circular buffer.
At Circular buffer, constantly receive interface display application and the interface display data that application is submitted to, and carry out after circular buffer, need to monitor in real time the interface display application in Circular buffer, to understand in real time the situation of the interface display application in Circular buffer.
In this embodiment, step S20 is specially: drive layer to create a separate threads, separate threads is monitored in real time to Circular buffer, and calls UpdateScreen operation and carry out interface display.Drive like this layer to create an independent separate threads, continue in real time the state of monitoring Circular buffer, monitored interface display application, will read out and process immediately, reach the effect of quick response; And by calling frequency UpdateScreen high and consuming time operation, put in separate threads and carry out, make to apply main thread and break away from and show high puzzlement consuming time, the smooth degree that improves application interface operation and show.
S30: obtain interface display application up-to-date in Circular buffer.
According to the real-time monitoring to Circular buffer, can understand write time and order that Circular buffer median surface shows application.According to monitored results, obtain all the time (finally writing) interface display application up-to-date in Circular buffer.
In this embodiment, step S30 is specially: drive layer to obtain mutual exclusion lock, obtain the authority that reads to Circular buffer, according to the real-time monitoring of Circular buffer is read to interface display application up-to-date in Circular buffer, after reading, discharge immediately mutual exclusion lock, loop (read next time and again obtain mutual exclusion lock, loop).Driving like this layer when the interface display application of the continuous buffer memory application of Circular buffer submission, obtain all the time current up-to-date interface display application, is also the interface display application that in Circular buffer, last buffer memory writes.For example, in Circular buffer, up-to-date interface display application is this moment m, obtains m this moment, next constantly in Circular buffer again buffer memory write interface display application n, the up-to-date interface display application that will obtain has become n, obtains n.
Simultaneously, for effectively saving space and the buffer efficiency of Circular buffer, step S30 further comprises: after obtaining interface display application up-to-date in Circular buffer, remove the interface display application of buffer memory before, to empty in time the space of Circular buffer, make Circular buffer in idle condition, to can carry out read-write operation at any time.
S40: call UpdateScreen operation, the corresponding interface display data of up-to-date interface display application are shown, this time demonstration is returned to step S30 after being finished and looped.
Driving layer in obtaining Circular buffer after up-to-date interface display application, calling UpdateScreen operates up-to-date interface display application is carried out, UpdateScreen operation shows the corresponding interface display data of up-to-date interface display application, thereby completes demonstration.After this demonstration executes, return to step S30 and continue to have circulated.At UpdateScreen, operate in and execute after a display operation like this, again obtain the interface display application that now (to complete the moment corresponding to current demonstration) up-to-date and carry out display operation, only now up-to-date interface display application is carried out to display operation, and do not carry out in the interface display application that waited in line in procedure for displaying last time, because application interface shows that finally always covering previous interface display application by up-to-date interface display application upgrades, and UpdateScreen operation is carried out and is once needed 50ms, recognition time much smaller than human eye, neglecting interface display application in UpdateScreen operation procedure for displaying can not watch and exerting an influence application interface display and user, avoided the interface display application of waiting in line too much to need to wait for the situation that just can be performed for a long time, thereby solved the problem that the interface display application waited in line too much causes serious card to pause, greatly guaranteed the smooth degree that application interface shows, greatly improve satisfaction of users.
In this embodiment, by separate threads, calling UpdateScreen operates.By a separate threads, call UpdateScreen operation separately, carry out Graphics Processing, do not take the main thread time of application, reach the fast operating of application and drive the demonstration of layer not interfere with each other, again can co-operating effect.
