Example IV
The embodiment of the present invention four is by adding camera model of the third-party coprocessor to mobile phone in the prior art Booting sequence is improved, and the following two kinds flow model be present:
The first flow model, 1, master chip (AP) notice coprocessor (Co-CPU) need open camera (CCM), read Last time setting/acquiescence CCM chip ids (identity);
2nd, a. master chips are prepared work, distribute the internal memory of storage image, configure the form of storage image, configuration diagram picture Signal processor (ISP);
B. whether the ID of coprocessor verification camera chip (CCM) is correct;It into step c, is not to read another CCM to be Chip id;
C. coprocessor configures to CCM, sets CCM setting (camera register);
3rd, CCM data flows (acquisition view data) are finally opened, start to transmit each frame image data, data are still transmitted Give AP ends ISP;
4th, ISP receives data, processing data form, after the completion of view data is transmitted to AP;
5th, AP display images, complete camera and start.
Second flow model (coprocessor in itself it is internal comprising internal memory and image processor ISP), 1, master chip (AP) notify coprocessor (Co-CPU) to need to open CCM, read it is last set/acquiescence CCM chip ids (identity);
2nd, a. coprocessors are prepared work, distribute the internal memory of storage image, configure the form of storage image, configuration ISP。
B. whether the ID of master chip verification camera chip (CCM) is correct;It into step c, is not to read another CCM cores to be Piece ID;
C. master chip configures to CCM, sets CCM setting (camera register);
3rd, CCM data flows (acquisition view data) are finally opened, start to transmit each frame image data, data are transferred to association Processor (Co-CPU) holds ISP;
4th, ISP receives data, processing data form, after the completion of view data is transmitted to AP;
5th, AP display images, complete camera and start.
The improvement of the embodiment of the present invention four is, the step of asynchronous execution, will make into synchronously to hold in original flow Capable a is with (b, c);Total time can be performed the summation of time by each step before, be changed to other steps and performed time sum, Summation with step a or with step b and c the execution time (selected value larger execution time).
In addition, Memory Allocation can not will have to release, next time in ISP in second of flow model after Memory Allocation Reallocate direct use, such speed can be faster.
The two kinds of flow models provided below the embodiment of the present invention four are specifically described.
For the first flow model, the camera on mobile phone need to meet following condition with coprocessor:
A.AP can communicate with coprocessor;
B. coprocessor (Co-CPU) can control CCM;
C.CCM data can be transmitted to the ISP at AP ends.
Concrete application flow is as shown in Figure 4:
Step 41:The request that user enters camera is received, into camera;
This step is that user opens camera applications, into camera to take pictures.
Step 42:AP notice coprocessors will open CCM;
This step is that AP ends receive the message for opening camera, and notice coprocessor will open CCM.
Step 43:This step is AP storage allocations, configures ISP and coprocessor initialization CCM is parallel, so can resolve into Several small steps below;
AP ends:
A.AP ends storage allocation;
B.AP ends set the form for receiving (storage) image;
C.AP ends configuration ISP processors (initialization, arrange parameter, set performance);
Coprocessor:
D. coprocessor verification CCM ID;
E. coprocessor sets CCM setting.
AP ends are parallel with coprocessor two parts step.
Step 44:Camera is opened, obtains view data, opens CCM data flows, starts output data;
This step is that CCM data flow is opened after obtaining the notice that two parts work is all completed according to step 43, by data It is output to the ISP at AP ends.
Step 45:AP ends ISP is handled after receiving data, gives the data after the completion of processing to AP, display image.
After this step is the initial data obtained from step 44, AP is returned data to after the completion of being handled by ISP.
Step 46:Judge whether to exit camera, if so, into step 47, if it is not, return to step 45.
Step 47:Camera is closed in the request that camera is closed according to user;
The current processing mode of this step can discharge the internal memory that AP ends are applied, ISP state reductions, CCM state reductions;Certainly Can also, when closing camera, AP end memories do not discharge, or by CMM make standby it is standby/park mode, be configured so that The used time of parameter can be shorter, and processing speed can be faster.
For second of flow model, the camera on mobile phone need to meet following condition with coprocessor:
D.AP can communicate with coprocessor, can be communicated with CCM;
E. coprocessor (Co-CPU) can receive CCM data;
F.CCM data can be transmitted to coprocessor;
G. coprocessor includes physical memory, and can handle the ISP of image.
Concrete application flow is as shown in Figure 5:
Step 51:Receive user to ask into camera, into camera;
This step is that user opens camera applications, into camera to take pictures.
Step 52:AP notice coprocessors will open CCM;
This step is that AP ends receive the message for opening camera, and notice coprocessor will open CCM.
Step 53:Determine whether to start camera for the first time, if so, into step 55, if it is not, into step 54;
Step 54:AP ends verify CCM ID, set CCM setting, subsequently enter step 56.
Step 55:This step is that AP initialization CCM and coprocessor storage allocation and initial ISP are parallel, so can decompose Into following several small steps;
AP ends:
F.AP ends verification CCM ID;
G.AP ends initialization (setting) CCM setting.
Coprocessor:
H. coprocessor end configuration ISP processors (initialization, arrange parameter, performance is set);
I. coprocessor storage allocation;
J. coprocessor configuration picture format.
AP ends are parallel with coprocessor two parts step.
Step 56:Camera is opened, obtains view data, opens CCM data flows, starts output data;
This step is to obtain two parts notice for all completing of work according to 55 or obtain the verification of AP ends according to step 54 to set After, CCM data flow is opened, outputs data to the ISP at coprocessor end.
Step 57:Coprocessor end ISP is handled after receiving data, gives the data after the completion of processing to AP, display Image.
After this step is the initial data obtained from step 56, AP is returned data to after the completion of being handled by ISP.
Step 58:Judge whether to exit camera, if so, into step 59, if it is not, return to step 57.
Step 59:Camera is closed in the request that camera is closed according to user;
The current processing mode of this step will not discharge the internal memory that coprocessor end is applied, ISP states can not have to reduction, It is arranged to standby patterns, CCM state reductions (AP releases CMM is set), can so improves the speed for starting camera next time.
