Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
A computing machine of the present invention is supported the method for multi-section portable terminal downloaded software version, as shown in Figure 1, may further comprise the steps:
Step 101: the frequency parameter of configuration CPU, execution in step 102 afterwards;
Here, because portable terminal is in process of production during the downloaded software version, the screen of portable terminal is not lighted, and various peripherals are touch-screen, keyboard, wireless module etc. for example, all is not activated, at this moment, electric current is most of to be consumed on CPU, therefore, and can be by changing the frequency parameter of CPU, that is: by adjusting the running frequency of CPU, reach the purpose that reduces current drain;
Frequency range and the speed of download of the CPU of the power supply capacity of the USB Host of the employed computing machine of foundation, the number of USB interface, the number that need carry out the portable terminal of software version download simultaneously, portable terminal, the frequency parameter of configuration CPU; Wherein, need carry out the number of the number of the portable terminal that software version downloads simultaneously smaller or equal to USB interface; Frequency parameter for configuration CPU, give an example, generally, the power supply capacity of the USB Host of computing machine is 500mA, the number of USB interface is 8, when carrying out portable terminal production, in order to accelerate the speed of production of portable terminal, 8 USB interface need be used simultaneously, at this moment, the number that need carry out the portable terminal of software version download simultaneously is 8, on 500mA mean allocation to 8 portable terminal, then the electric current of each portable terminal is 62.5mA, afterwards according to 62.5mA, the frequency range of the CPU of portable terminal, and in conjunction with speed of download, the frequency parameter of configuration CPU; Wherein, on the chip handbook, provide the frequency range of the CPU of portable terminal, described in conjunction with speed of download, the frequency parameter of configuration CPU is meant: according to the frequency parameter of CPU, after the frequency of the CPU of adjustment portable terminal, when carrying out multi-section portable terminal downloaded software version simultaneously with a computing machine, the influence of the speed of download of every portable terminal is little, that is: after the frequency of the CPU that adjusts portable terminal, both supported to carry out multi-section portable terminal downloaded software version simultaneously, and speed of download had not been had influence substantially with a computing machine;
The frequency parameter of described CPU comprises: the value of the value of the value of global clock frequency division register, output source clock division register, the value of phaselocked loop mode register, phaselocked loop Frequency Dividing Factor L, the value of phaselocked loop Frequency Dividing Factor M, the value of phaselocked loop Frequency Dividing Factor N;
In actual application, the frequency parameter of the CPU of described configuration can be formed a new configuration file, the content of described new configuration file is the tabulation of register and its respective value, promptly can obtain content as follows:
1. global clock frequency division register, 0x15;
2. output source clock division register, 0x5200;
3. phaselocked loop mode register, 0x2;
4. phaselocked loop Frequency Dividing Factor L, 0x32;
5. phaselocked loop Frequency Dividing Factor M, 0x0;
6. phaselocked loop Frequency Dividing Factor N, 0x6;
Wherein, phaselocked loop Frequency Dividing Factor L, phaselocked loop Frequency Dividing Factor M and phaselocked loop Frequency Dividing Factor N also are registers, in actual use, can at first enter the read-only memory (ROM that chip internal solidifies behind the mobile terminal-opening, Read-Only Memory) program, because this program is pre-configured before the chip of portable terminal dispatches from the factory, therefore, can not make any modification, that is: can be behind the mobile terminal-opening according to the frequency parameter operation of the CPU that configures, pre-configured configuration file back before if described new configuration file directly is added in and dispatches from the factory, because pre-configured configuration file or described new configuration file before ROM can not identify and dispatch from the factory, can occur earlier according to after the configuration file configuration successful pre-configured before dispatching from the factory, dispose again once according to described new configuration file again, at this moment, the frequency of CPU is the frequency of the CPU of described new configuration file, frequency when the frequency of CPU is lower than normal the use, so, can influence the normal use of portable terminal, therefore, the register that adds a free time in the middle of can be before described dispatching from the factory pre-configured configuration file and the described new configuration file, the numbering of the register of described free time need be through careful design, that is: the unloading phase of ROM, the register of described free time is an actual non-existent dummy register, the numbering of the register of described free time is taken as 0xFFFFFFFF, because 0xFFFFFFFF is the address value of a maximum, it also is a retention, therefore, any a chip all can not have register and use this address.So when carrying out this register, the rreturn value of configuration result is bound to be " vacation ", so, described new configuration file just can not be configured, thereby can not influence the frequency of the CPU when starting shooting normal interface; When downloading start, adjust and comprise the relevant information of distinguishing configuration file pre-configured before described new configuration file and described the dispatching from the factory in the code of frequency of CPU, in view of the above, can read described new configuration file.
Step 102: behind the mobile terminal-opening, judge whether the start reason is to download start, after being defined as downloading start, adjust the frequency of CPU, enter the download flow process afterwards according to the frequency parameter of the CPU of configuration;
Here, before judging whether the start reason is the download start, this method can further include:
Carry out the ROM program of the chip internal curing of portable terminal;
Particularly, the frequency parameter of pre-configured CPU before the ROM program reads in portable terminal from flash memory (Flash) chip dispatches from the factory, the frequency of the CPU when normally being used according to the frequency parameter of CPU;
Whether described judgement start reason is to download start, is specially:
The button that uses during according to start judges whether the start reason is to download start; Perhaps,
During mobile terminal-opening, judge whether portable terminal is equipped with battery; Perhaps,
Behind the mobile terminal-opening, whether can find the flag of setting;
Wherein, portable terminal only can use the power key start when normal the use, and in process of production, directly enter when downloading start, different key modes can be set, such as: be provided with and press simultaneously on the volume under the key and volume behind the key, press power key afterwards again, directly enter and download start;
In actual application, if portable terminal directly enters when downloading start, can be with after USB interface of computer be connected, the power supply capacity by USB interface directly enters portable terminal and downloads start, at this moment, portable terminal is not equipped with battery, and portable terminal need could be started shooting by battery, therefore when normal the use, in the time of can be by mobile terminal-opening whether battery be housed, judges whether portable terminal is to enter to download start;
In the production run of portable terminal, a flag can also be set in advance, behind the mobile terminal-opening in the internal memory of portable terminal, can go to seek described flag, if can find, then explanation is to download start, if do not find, then explanation is the normal start of using; After download is finished, delete this flag, in order to avoid influence the normal use start of portable terminal;
The frequency parameter of described CPU according to configuration is adjusted the frequency of CPU, is specially:
From internal memory, read the frequency parameter of the CPU of described configuration, and according to the frequency parameter of the CPU of described configuration, the operation that the register of frequency parameter correspondence is read or write; Wherein, the described operation that the register of frequency parameter correspondence is read or write is meant the content that reads register or writes content in register; Determine register is carried out read operation or write operation according to the attribute of register, prior art has been carried out specified in more detail to the attribute of register.
When practical application, the code of adjusting the frequency of CPU can be placed on operation in the inner buffer (IMEM), guarantee that CPU Double Data Rate synchronous DRAM (DDR) when switching of portable terminal is unavailable, that is: can not have influence on the execution of code;
Determine it is not when downloading start, not carry out any operation.
Below in conjunction with embodiment the present invention is further described again.
The application scenarios of present embodiment is: the chip that portable terminal adopted is high pass (Qualcomm) platform 7x25 or 7x27, and when normal the use, the frequency of CPU is 400MHz.
Need in the present embodiment electric current is adjusted between 60 to 80mA, and then realize that a computing machine supports multi-section portable terminal downloaded software version simultaneously, and the little purpose of speed of download influence, therefore, the content of new configuration file is specially:
1. global clock frequency division register, 0x15;
2. output source clock division register, 0x5200;
3. phaselocked loop mode register, 0x2;
4. phaselocked loop Frequency Dividing Factor L, 0x32;
5. phaselocked loop Frequency Dividing Factor M, 0x0;
6. phaselocked loop Frequency Dividing Factor N, 0x6;
New configuration file needs the definition of accord with Q ualcomm, new configuration file is saved in the internal memory of portable terminal, and the register that before dispatching from the factory, adds a free time in the middle of pre-configured configuration file and the described new configuration file, the numbering of the register of described free time is taken as 0xFFFFFFFF, no matter Qualcomm company is in the past, still any a chip of producing in the future all can not have register and use this address now, when carrying out this register, the rreturn value of configuration result is bound to be " vacation ", thereby can not influence the frequency of the CPU when starting shooting normal interface;
