Description

Accelerate the method for handset starting response speed

Technical field

The present invention relates to the wireless communication terminal apparatus field, particularly relevant a kind of method of accelerating handset starting response speed.

Background technology

The start process of mobile communication equipments such as mobile phone is the process of a more complicated, presses the start key from the user, generally can experience process as described in Figure 1.

At first system powers on, and occurs the initialization screen after system powers on, and boot animation then occurs, changes standby picture into by boot animation again.

Press the start key from the user and power on to system and the initialization screen occurs, generally be controlled in 3 seconds,, generally be controlled in 10 seconds to stable standby picture occurring from the initialization screen, whole process is about 13 seconds.If long during this period of time, particularly, will influence user's use from pressing the start key to the long during this period of time of initialization screen occurring.Here the user being pressed the start key, to begin to this section timing definition that the initialization screen occurs be the system boot response time, and the start response time of general cell phone system is all in 3 seconds.

On system, start process roughly is such: the user presses the start key and causes cpu reset, and CPU then begins run time version from chip guide, and this section code is generally all very short, mainly finish the initialization of CPU and some hardware devices, dual mode operation below selecting then:

If what 1 system adopted is parallel flash memory chip, will jumps on the flash memory chip and directly carry out;

If 2 employings is the serial flash memory chip, because direct working procedure above the serial flash memory chip, so must at first copy program in the random asccess memory (RAM, Random Access Memory) to, jump in the random asccess memory then and carry out;

Flash memory chip (Flash) is divided into two types of NAND (with non-) and NOR (or non-), and its main distinction is the different of its mode of operation and access time.NAND type Flash is referred to as serial Flash usually, and its operational order, operation address and operating data are by same 8 bus transfer, has less hardware and connects.NOR type Flash is referred to as parallel Flash usually, and its address bus and data/address bus separate, and access speed is very fast, but the hardware connection is more.

If what system adopted is the serial flash memory chip, its relative low price, copy in the Installed System Memory owing to must at first take time program and data, cause system to power on interior screen of back a very long time like this without any reaction, the system start-up overlong time, delay of response influences user's use, thereby makes product lose the user.

Summary of the invention

The object of the present invention is to provide a kind of method of accelerating handset starting response speed,, solve the problem that prior art can't start mobile phone fast to overcome above-mentioned the deficiencies in the prior art.

For achieving the above object, the invention provides a kind of method of accelerating handset starting response speed, may further comprise the steps: a. system powers on; B. start-up routine module the copy operation software and data copy module jumps to random asccess memory and carries out after random asccess memory from flash memory chip; C. set up the multiple task operating system environment, start the human-computer dialogue task, create the background copy task; D., the initialization screen appears; When e. showing boot animation, all the other modules of copy operation system and continue to load start all modules to random asccess memory from flash memory chip; F. show standby picture.

Wherein, described flash memory chip right and wrong type flash memory chip.Described all the other modules are meant each hardware drive program of mobile phone.Described random asccess memory is a synchronous dynamic random access memory.

The present invention is led to and is planned as a whole to optimize on the basis that the mobile phone power-on time spent is analyzed, and has proposed a kind of effective shortening system start-up time, improves the method for system boot response simultaneously, improves product usefulness greatly.The present invention can with non-type flash memory chip on, realize the same start process rapidly with the or/no type flash memory chip.Shortened at least 6 seconds whole start-up time, improved the performance of mobile phone significantly.The present invention does not add any new element and increases cost, has but realized the function that prior art need adopt expensive components comparatively just can reach.

The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.

Embodiment

Relevant detailed description of the present invention and technology contents, existing as follows with regard to accompanying drawings:

At first see also Fig. 2, Fig. 2 is a mobile phone internal structure schematic diagram of having simplified.Mobile phone hardware structure among Fig. 2 comprises as devices such as keyboard, loudspeaker and audio decoder, antenna and radio frequency processing, batteries, core circuit partly comprises: power management and analog signal processing chip, SDRAM (Synchronous Dynamic Random Access Memory, synchronous dynamic random access memory), microprocessor (MCU), accelerator, with non-type (NAND) flash memory chip, these chips are that core constitutes control circuit with the microprocessor, control such as unit such as serial data interface, camera, music by the software module in the operating system.

Wherein be mainly used to stand-by program and data with NOT-AND flash reservoir chip, synchronous dynamic random access memory is to be used for loading and the internal memory of working procedure.Need be during start with operating system software from copying to synchronous dynamic random access memory with NOT-AND flash reservoir chip.Here also can the flash memory chip of other types with NOT-AND flash reservoir chip; Synchronous dynamic random access memory also can be the random asccess memory (RAM) of other types.

With the reading speed of NOT-AND flash reservoir chip greatly about 10 MBPSs to about 20 MBPSs, for the system of one 16 Mbytes, copy time the random asccess memory to from the flash memory chip and minimumly be:

16 Mbytes *, 8/20 MBPS=6.4 seconds

This time is extra expense.Though the random asccess memory speed of service is more a lot of soon than flash memory chip, but system configuration with respect to or/no type flash memory chip+random asccess memory, still will grow at least about 6 seconds with the start response time under NOT-AND flash reservoir chip+accidental memory structure, this is unacceptable.

See also Fig. 3, Fig. 3 is a mobile phone power-on schematic flow sheet of the present invention.In mobile phone power-on flow process of the present invention, at first system powers on; Then start-up routine module the copy operation software and data copy module jumps to random asccess memory and carries out after random asccess memory from flash memory chip; Set up the multiple task operating system environment, start the human-computer dialogue task, create the background copy task; The screen initialization appears; When showing boot animation, all the other modules of copy operation system and continue to load and start all modules to random asccess memory from flash memory chip; Show standby picture at last.All the other modules here are meant each hardware drive program of mobile phone, unit such as serial data interface as mentioned above, camera, music.

The present invention has realized a two-wire journey start-up course by planning as a whole optimization by background copy, loading like this.An original copy function is become twice copy function.After system powers on, copy operation system and data copy module two parts are in random asccess memory, set up multiple task operating system then, create a background task simultaneously, the boot animation stage in start process is duplicated remaining module to random asccess memory from the flash memory chip simultaneously.

See also Fig. 4 A, B, Fig. 4 A, B are prior art and time spent of the present invention contrast schematic diagram.Can learn that the present invention has shortened the available machine time significantly.

Represent among Fig. 4 A of prior art, supposing that system powers on needs 3 seconds, and according to computing formula above-mentioned, duplicating all operations systems soft ware needs 6.4 seconds, and system start-up and demonstration boot animation amount to and need 10 seconds, and start process needs 19.4 seconds altogether so.

Represent among Fig. 4 B of the present invention, suppose that it also is 3 seconds that system powers on, owing to only duplicate start-up routine module and data copy module, these two modules amount to size and are about 500K, and then doubling time is:

500K*8/20 MBPS=0.2 second.

Duplicate other part operation systems soft wares and system start-up and the demonstration boot animation carries out simultaneously, added so 10 seconds, then start process 13.2 seconds times spent altogether.

Obviously,, can ignore basically in 0.2 second with respect to 6.4 seconds, so just can with NOT-AND flash reservoir chip on, realize the same start process rapidly with or/no type flash memory chip.Shortened at least 6 seconds whole start-up time.

The above introduction only is preferred embodiment of the present invention, can not limit scope of the invention process with this.The variation that is equal to that those skilled in the art in the present technique field are done according to the present invention, for example each step among the above embodiment is made up, or add components and parts beyond the components and parts that the present invention mentions, the mobile phone power-on flow process is done equivalent variations or apparent and easy to know derivation, and the improvement known of those skilled in that art, all should still belong to the scope that patent of the present invention contains.
