Embodiment two
See Fig. 3, it is the structural representation of a kind of intelligent terminal that the embodiment of the present invention provides.In the present embodiment, the explanation of related content can with reference to above.Intelligent terminal 3 shown in Fig. 3 comprises: receiver module 31, control module 32, cache module 33 and execution module 34.
Receiver module 31, for receiving the empty mouse data from radio-frequency (RF) remote.
Control module 32, for the empty mouse data write cache module 33 received by receiver module 31; And from cache module 33, read empty mouse data with constant speed.
Execution module 34, for performing the operation of control module 32 from cache module indicated by the 33 empty mouse data read.
By the radio-frequency (RF) remote described in embodiment one, annexation between radio frequency receiver and intelligent terminal, known, receiver module 31 is specifically for the empty mouse data of received RF receiver transmission; Wherein, these sky mouse data are the data obtained after radio frequency receiver is resolved the received radiofrequency signal sent by radio-frequency (RF) remote, and namely the sensor of radio-frequency (RF) remote detects the related data obtained.
" cache module 33 " is a part of storage space that the embodiment of the present invention is opened up specially in order to the technical matters solved in background technology in intelligent terminal 3.Receiver module 31 receives the speed of empty mouse data and the hardware of intelligent terminal 3 or the configuration etc. of software and the writing rate of the empty mouse data in cache module 33 may be caused non-constant; The reading rate of the empty mouse data in cache module 33 is constant value.Therefore, the effect of cache module 33 can be understood as: the transfer rate of empty mouse data is become constant value from inconstant value.Wherein, radio-frequency (RF) remote sends the speed etc. that the speed of radiofrequency signal, the speed of radio frequency receiver received RF signal and radio frequency receiver resolve radiofrequency signal, can affect the speed that receiver module 31 receives empty mouse data.
Control module 32 is when performing the empty mouse data write cache module 33 received by receiver module 31, specifically may be used for: receiver module 31 is detected, and after detecting that receiver module 31 have received the empty mouse data of a frame, by this frame empty mouse data write cache module 33. at every turn
Control module 32, when execution reads empty mouse data with constant speed from cache module 33, specifically may be used for: from cache module 33, read the empty mouse data of a frame every fixed time interval.Further, empty for this frame mouse data are transferred to execution module 34.Optionally, control module 32 after the empty mouse data of reading one frame, can delete the empty mouse data of this frame in cache module 33; The empty mouse data grows of cache module 33 can be prevented so many, thus take too many storage space, affect the overall performance of intelligent terminal 3.
Execution module 34 is specifically as follows treatment progress or uinput (virtual input) equipment etc.; Performed operation is specifically as follows cursor and moves operation, cursor positioning action etc.It should be noted that, during specific implementation, a frame or multiframe data are used to indicate same operation.
The intelligent terminal that the present embodiment provides comprises receiver module, control module, cache module and execution module, and receiver module is for receiving the empty mouse data from radio-frequency (RF) remote; Control module is used for the empty mouse data write cache module received by receiver module, and from cache module, reads empty mouse data with constant speed; Execution module is for the operation indicated by the empty mouse data that perform control module and read from cache module.Like this, the constant rate of the empty mouse data of input execution module can be made, thus make movement or the position fixing process smooth of the cursor on intelligent terminal, decrease the probability occurring Caton phenomenon and motion blur phenomenon, improve the experience of user.
Optionally, control module 32 specifically for: based on the principle of first in first out, from cache module 33, read empty mouse data with constant speed.Concrete: according to time order and function order, the empty mouse data being first written into cache module 33 are first read.Like this, effectively can ensure that the order of the operation performed by execution module 34 is consistent with the sequence of operation indicated by the empty mouse data received by receiver module 33.For example, during specific implementation, control module 32 according to the time order and function order of write cache module 33, can be numbered the empty mouse data of the every frame in write cache module 33, then reads empty mouse data according to the numbering of the empty mouse data of each frame.
Optionally, as shown in Figure 3, control module 32 comprises timing unit 321, and timing unit 321 is for arranging timing; Control module 32 specifically for: when the timing of timing unit 321 arrives, from cache module 33, read the empty mouse data of a frame.The embodiment of the present invention does not limit the concrete value of timing and the obtain manner of this concrete value, hereinafter provides a kind of optional implementation determining timing.
Timing unit 321 can be a high-precision timing unit, and concrete, its precision can reach nanosecond.During specific implementation, intelligent terminal 3 when process initialization, can create timing unit 321.To realize the reading rate of the empty mouse data in cache module 33 constant, simple and convenient by arranging timing unit 321 for this optional implementation, and the real-time of system can be made better.
For example, in the software of intelligent terminal, the operation such as reception, process of empty mouse data all completes in a process, thread can be created ceaselessly from the empty mouse data in bottom UART (UniversalAsynchronousReceiver/Transmitter, the universal asynchronous receiving-transmitting transmitter) buffer memory of intelligent terminal 3 in cache module 33 in process; Also can create timing unit 321 in process, thus utilize timing unit 321 realize Timing Processing and export empty mouse data.Concrete, when process initialization, timing unit 321 can be created.
In the optional implementation of one, control module 32, also for receiving the capacity of the empty mouse data that receiver module 31 receives in the speed of empty mouse data or preset time period according to receiver module 31, determines the capacity of cache module 33.
If the capacity of cache module 33 is less, then when the speed that receiver module 31 receives empty mouse data is comparatively large or in preset time period, the capacity of the empty mouse data that receiver module 31 receives is larger, the follow-up empty mouse data transmitted from receiver module 31 can be caused cache module 33 can not be written into because the storage space in cache module 33 is entirely occupied, or cause the empty mouse data write in cache module 33 not also to be able to do in time to be read under the control of control module 32, just by the follow-up empty mouse data cover transmitted from receiver module 31; Both of these case all can cause the loss of data of sky mouse.If the capacity of cache module 33 is comparatively large, namely the capacity of cache module 33 accounts for the large percentage of the power system capacity of intelligent terminal 3, then can consume too many system resource.Therefore, during specific implementation, need the capacity that cache module 33 is rationally set.
For example, control module 32 capacity of empty mouse data that receiver module in preset time period 31 can be received is as the capacity of cache module 33; Or, in preset time period the empty mouse data that receiver module 31 receives capacity based on an amount of floating as the capacity of cache module 33.Such as, preset time period is 1s (second), then can using the capacity of empty mouse data that receives in the 1s capacity as cache module 33; Or using receive in 1s 80%, 90%, 110% or 120% of the capacity of empty mouse data etc. as the capacity of cache module 33.
The speed that " receiver module 31 receives the speed of empty mouse data " sends radiofrequency signal primarily of radio-frequency (RF) remote determines.In theory, receiver module 31 receives the speed that the speed of empty mouse data and radio-frequency (RF) remote send radiofrequency signal; In fact, can due to factors such as the transmission environment of radiofrequency signal, the forward efficiencies of radio frequency receiver, the speed making receiver module 31 receive empty mouse data is less than the speed that radio-frequency (RF) remote sends radiofrequency signal.
The capacity of the empty mouse data that receiver module 31 receives " in the preset time period " can receive the speed of empty mouse data according to receiver module 31, determine with the size of this preset time period.
In the optional implementation of one, control module 32, also for receiving at least one in the system time of the speed of empty mouse data and the complete machine process scheduling of intelligent terminal 3 according to receiver module 31, determine constant speed (reading rates of the empty mouse data namely in cache module 33).
This optional implementation, for determining the reading rate of the empty mouse data in cache module 33, in other words, determines the size of " timing ".Wherein, if timing is too large, then the response speed of intelligent terminal 3 radio frequency telepilot can be caused slower; If timing is too short, extreme case is that the empty mouse data of write cache module 33 are read to execution module 34 immediately, such meeting causes the speed of the empty mouse data inputting execution module 34 non-constant because output speed is too fast, thus the technical scheme causing not having the embodiment of the present invention and provide wants the technique effect that reaches.Therefore, during specific implementation, need the reading rate of the empty mouse data rationally arranged in cache module 33.
For example, control module 32 receives the speed determination reading rate of empty mouse data according to receiver module 31, be specifically as follows: control module 32 determines the mean speed of the empty mouse data that receiver module 31 receives in each time cycle of multiple time cycle, and using the reading rate of the average of the plurality of mean speed as the empty mouse data in cache module 33.Such as, suppose that the mean speed of the empty mouse data that receiver module 31 receives in two time cycles that control module 32 is determined is respectively A and B, then can using (A+B)/as the reading rate of the empty mouse data in cache module 33.
Because empty mouse data complete in a process of intelligent terminal 3; If complete machine configuration is lower, CPU (CentralProcessingUnit, central processing unit) resource is nervous, and process execution efficiency is low, then the speed reading empty mouse data is slower; Otherwise process scheduling is fast, and the speed reading empty mouse data is faster.Therefore, " system time of the complete machine process scheduling of intelligent terminal 3 " also can have influence on the reading rate of the empty mouse data in cache module 33.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
