The present invention solves the technical scheme that above-mentioned primary technical problem adopts: a kind of keyboard multiplexing management system, it includes baseband processor, coprocessor, keyboard and external equipment, keyboard is connected with baseband processor hardware, it is characterized in that keyboard is connected with coprocessor hardware simultaneously, and baseband processor is the manager of keyboard logic function all the time, keeps the control of keyboard or will temporarily consign to coprocessor to the control of keyboard.
The present invention solves the technical scheme that above-mentioned another technical problem adopts: a kind of keyboard multiplexing management method, it relates to baseband processor, coprocessor, keyboard and external equipment, keyboard is connected with baseband processor hardware, it is characterized in that keyboard is connected with coprocessor hardware simultaneously, and, baseband processor and coprocessor all can directly respond the action of keyboard, baseband processor is the manager of keyboard logic function all the time, maintenance is to the control of keyboard or will temporarily consign to coprocessor to the control of keyboard, after coprocessor obtains the keyboard administrative power from baseband processor, directly respond the action of keyboard independently, regain its control keyboard up to baseband processor.
Its keyboard multiplexing management performing step on software is:
(a) mobile phone is in holding state;
(b) judge whether baseband processor receives the request of giving coprocessor about with Keyboard Control power;
(b1) be to enter (c) step;
(b2) not, return (a) step;
(c) judge whether baseband processor agrees the request of giving coprocessor with Keyboard Control power;
(c1) be to enter (d) step;
(c2) not, return (a) step;
(d) baseband processor is provided with the flag bit that accordingly Keyboard Control power is shifted--and give corresponding coprocessor with Keyboard Control power, corresponding program is moved on coprocessor, and coprocessor response keyboard.Baseband processor is given coprocessor with Keyboard Control power, when can be understood as baseband processor and allow program to move on coprocessor, gives coprocessor with Keyboard Control power;
(e) Dui Ying EP (end of program) proposes to return the request that Keyboard Control is weighed to baseband processor;
(f) baseband processor is agreed this request, and recovers accordingly Keyboard Control to be weighed the flag bit that shifts--Keyboard Control power is regained;
(g) return (a) step.
The base band primary processor always can be enjoyed authority at the highest level to keyboard, and it can give coprocessor with Keyboard Control power, allows coprocessor that keyboard is managed, and certainly, it also can be regained this authority.Coprocessor is controlled by baseband processor in the whole process, and coprocessor can not determine oneself whether keyboard to be enjoyed the authority of management.Such as incoming call being arranged in the game process, come short message, come multimedia message or the like, the preferential supervisory keyboard of baseband processor is promptly enjoyed the preferential control to keyboard.
In the entire work process of coprocessor, because the existence of the agreement between the connection of the hardware between baseband processor and the coprocessor or software such as baseband processor and the coprocessor etc., remain communication between baseband processor and the coprocessor, and baseband processor keeps the monitoring to coprocessor always, when being necessary, regain the control of keyboard.For example; there is emergency to take place; such as incoming call; then baseband processor automatic drawing back Keyboard Control is weighed; suspend or stop current program in the coprocessor operation; by the time this emergency disposes and finishes as receiving calls, and Keyboard Control power is given coprocessor again, proceeds or restarts in the program of coprocessor operation.
Other emergency, as user's forced shutdown or because under the situation of situations such as battery electric quantity deficiency shutdown, then directly shutdown.Next time is when starting shooting, because the initialization of whole system, baseband processor is enjoyed Keyboard Control power.
Baseband processor is the effector of keyboard logic function all the time, and its is according to the connection of own decision to coprocessor release physical keyboard, and also according to request (EP (end of program)) the withdrawal connection of own decision (emergency) or coprocessor.
Except that some picture recreation and mobile TV or the like those need be the program of moving on the coprocessor, traditional application program of base band such as short message processing, phone directory processing etc. can realize by the response of baseband processor to keyboard.When the user uses these special when needing the situation application program of application coprocessor such as recreation and mobile TV etc., baseband processor has just been given coprocessor with the control of keyboard.For button,, there are following two types usually according to the difference of its function:
Closing key-＞key hereto, because relate to closing of system, baseband processor limits this key and is responded by coprocessor.Baseband processor keeps the response to closing key always.(general length is then shut down by this key, and weak point then withdraws from current program by this key)
Function key-＞(all keys of other except that closing key are function key, these function keys can be as the function key of coprocessor) control of keyboard is when coprocessor, coprocessor responds described function key, and baseband processor does not respond described function key.
The control of keyboard is when baseband processor, and coprocessor does not participate in work, and coprocessor does not respond described function key, and baseband processor responds described function key.
That is: as special case, closing key is controlled by baseband processor only.
In the design concept of this keyboard multiplexing software, the double-mode of keyboard is its feature, and it comprises two patterns, and these two kinds of patterns can be judged by " Status Flag ".
(1) baseband mode: the base band primary processor manages keyboard, and all physical keyboards all have been set up corresponding call back function, is used for realizing the MMI (man-machine interface interface) that is correlated with.
(2) coprocessor pattern: the keyboard state of original base band primary processor management is set to " Physical NO " (" Physical NO " can be interpreted as " not connecting in logic ") pattern, (can be understood as by flag bit and distinguish or discern different mode) coprocessor so just can manage keyboard, and promptly the control of keyboard has been given coprocessor.In this state, when some function keys are pressed, in coprocessor, have a corresponding special function to be called, parameter at this moment be the key assignments (Key ID) of corresponding keyboard and correspondence relevant with coprocessor " call back function " (callback).
Compared with prior art, the invention has the advantages that:
(1) utilized base band and coprocessor both sides' advantage better, made the advantage of " base band primary processor+coprocessor " this platform framework perform to optimum state;
(2) processing speed is fast, makes system's operation more stable, optimizes the system operation.Be not easy specifically to crash;
(3) make system possess stronger autgmentability, if the promptly follow-up coprocessor that needs to increase other can directly link to each other this coprocessor with keyboard, and can be so that this coprocessor can directly respond keyboard.Realize the expansion of system thus.
