Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method for starting up mobile terminal.
Background technology
TD-SCDMA is in the early stage of formal commercialization now as the 3G (Third Generation) Moblie standard that China proposes, and is about to large-scale commercial.At present existing how tame manufacturer provides TD-SCDMA terminal solution.Two kinds of non-power-failure volatile memory of main employing are used for storing embedded program in these schemes: NOR type and NAND type, need at random storage-type memory PSRAM (Pseudo Static RandomAccess Memory, pseudo-static random access memory) or SDRAM to come working procedure in addition.
These schemes mostly adopt NOR FLASH and PSRAM as memory.And the Boot code is solidificated among the Rom of baseband chip, at first can carry out after powering on from the Boot code of chip internal, carry out after the code of outside Nor Flash, carry out the initialization of external devices and other functions, program start is slower, and the available machine time is long, uses very inconvenient.
Its start process is: at first pin power key, battery is given ABB (Analog Baseband Processor, the Analog Baseband process chip) power supply, ABB gives DBB (Digital Baseband Processor, digital baseband process chip) power supply, and produces reset signal, CPU Rom place internally begins to get the finger execution, the Boot program of inner Rom detects whether locking equipment of internal bus, then enters downloading process if having, if there is not the initial address operation main program that then jumps to flash memories; Finish memory address mapping, clock adjustment, configuration register and initialization running environment etc. in the main program initialization procedure; Follow-up initialization system hardware and the operating system initialization system of carrying out;
After more than being finished, carry out the picture processing chip initialization, the initialization of display screen also shows start-up picture;
The problem that this start process exists: bootup process and start power supply are held concurrently the hardware detection time, add the initialization of main program system and operating system, to LCD initialization and demonstration start LOG picture, relative user of this time is just long, cause the user to feel to start shooting slow, reduced user satisfaction.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of portable terminal to start the method for demonstration fast.
In order to solve the problems of the technologies described above, the present invention proposes a kind of method for starting up mobile terminal, and it is preposition with image processor initialization and display screen initialization step, carries out the step that shows the start interface after this step is finished.
Wherein, described image processor initialization and display screen initialization step are arranged at and jump to before the main program.
Wherein, described image processor initialization and display screen initialization step are arranged at before the operating system initialization.
Wherein, described image processor initialization and display screen initialization step are arranged at after the baseband processor initialization.
Further, the step that comprises the initialized step of system environments, the initialized step of baseband processor, image processor initialization and the initialized step of display screen, the initialized step of main program, the initialized step of software and hardware and operating system and application initializes.
The initialized step of wherein said system environments comprises the initialized process of storehouse;
The initialized step of described baseband processor comprises flash memory initialization, random asccess memory initialization, configuring external interface bus, be provided with that baseband processor powers on and baseband processor in the initialized process of control mouth.
In addition, the initialized step of described system environments also comprises the process that enters System Management Mode; The initialized step of described baseband processor also comprises the process of phase-locked loop with the realization frequency multiplication that be provided with.
Wherein, described image processor initialization comprises that the image processor power supply enables, the image processor clock enables and image processor resets, and starts the Bypass function;
Described display screen initialization comprises that display screen resets and shields initiation parameter configuration.
Wherein, the analog designation program designation that is provided with in the flash memories of described start-up course by described portable terminal is finished.
Wherein, described main program initialization does not comprise the operation of having carried out.
The present invention in case described initialization is finished, just can show the start interface owing to the initialization with image processor and display screen moves to front end, so, has reduced user's stand-by period greatly, has improved user satisfaction.

After this step finished, portable terminal just showed the start interface;
Step S24, the main program initialization.
In this step, jump to behind the main program and just carry out, just no longer carry out, for example the display screen initialization operation among the step S23 etc. in the operation that this process has been carried out according to main program code;
Step S25, the software and hardware initialization.
This step is mainly carried out the initialization of some peripheral hardwares, to finish complete start flow process; For example, to initialization of keyboard, bluetooth module, infrared module and mains switch or the like;
Step S26, operating system initialization.
Realize the initialization to embedded OS in this step, for example Linux, WinCE, PalmOS, Symbian, ThreadX operating system etc. mainly comprise the establishment of each static thread of operating system and registration or the like; Because the initialization of various operating systems is all similar, and its initialization procedure also all is known technology, therefore is not explained in detail at this;
Step S27, application initializes.
The initialization that is primarily implemented in the upper layer application on the operating system of this step; For example, to initialization of player, menu, dialog box, address list or the like;
Step S28, standby.That is, whole starting up's process finishes, and portable terminal enters user mode and carries out standby;
Step S29 finishes.
With reference to figure 3, illustrate the flow chart that the present invention starts another embodiment of method.As shown in the figure, present embodiment is based on arm processor, and after the user pressed the start key, battery was powered to ABB, and ABB is to the DBB power supply and produce reset signal, and follow-up may further comprise the steps:
