Embodiment
Core of the present invention is the internal memory of veneer in the equipment is divided into different storage areas, the repositioning information under the different conditions is stored respectively, and repositioning information is saved in the power down maintenance medium.
The present technique field personnel know, resetting of equipment has following several types usually: electrification reset, cold reset (cry not only hard reset), hot reset (but also crying warm reset), push-button reset, hardware dog reset, dongle reset etc.Wherein,
Electrification reset: i.e. Board Power up software startup is meant resetting that veneer whenever powers on and once produce.
Cold reset: CPU and crucial business chip are such as DSP (digital signal processing) chip, FPGA (programmable logic array) chip reset.
Hot reset: cpu reset or software rerun, but the key business chip does not reset.It generally is the positive return of software.
Push-button reset:, generally be manual operation by resetting that the button on the veneer causes.
Hardware dog reset: the hardware watchdog circuit overflows resetting of the CPU that causes or business chip.
Dongle resets: find in the software running process that CPU usage is the software positive return that caused for a long time at 100% o'clock.
For these different reset types, electrification reset, cold reset, push-button reset, hardware dog reset wherein can be referred to as hardware reset; Wherein hot reset, dongle resetted be referred to as the software reset.
Because the startup of appliance services software needs the guiding of BIOS, therefore know that at first the software of current reset circuit is BIOS (basic input/output), so just need a mechanism that the repositioning information that inquires among the BIOS is passed to software, by software it being recorded power down again keeps in the medium, such as, be saved among the FLASH (flash memory).
The present invention just is based on above-mentioned thought, by BIOS different reset types is discerned when device start, the repositioning information of different conditions is carried out effective, complete record, for inquiry.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 2, Fig. 2 is the process flow diagram of the inventive method, may further comprise the steps:
Step 201: the repositioning information shared memory is set in the internal memory of equipment.
With this shared memory as reserved memory, be used for the temporary and transmission of repositioning information, for example, with internal memory foremost or one section space of rearmost end as shared memory, this section space is sightless for operating system and general procedure user, so this section storage space can not rewritten or remove.
The present technique field personnel know, BIOS also can be regarded as a kind of software, but it and general software have important difference again, because of it closely links to each other with device hardware, be responsible for responsibilities such as the most important basic input/output routine of preservation equipment, system's configuration information, startup power on self detection program and system start-up self-check program.After equipment was connected with the mains and started, BIOS just began to take over all self check work of device start.Usually, system is at first come inner each unit is checked by the power-on self-test program, comprises CPU, internal memory, ROM, serial paralled interface etc. are tested; BIOS just reads in the booting operating system record then, gives leader record with system's control at last, by the program run of leader record guide service.If equipment is carried out hardware reset, such as, electrification reset, push-button reset etc., then BIOS need rerun, and system is reset; If produce the software reset in the business software operational process, then BIOS does not need system is reset, and only needs to get final product by leader record guide service program run again; If in the BIOS operational process, produce the BIOS positive return, need this repositioning information of record equally, so that accurately distinguish the different classifications that resets.
Therefore, in order to distinguish the classification that resets better, also need this shared memory is divided into first memory block and second memory block.Wherein, first memory block is used to preserve the repositioning information of business software, and second memory block is used to preserve the repositioning information of bios software, so that accurately distinguish the classification that resets.
Step 202: when the software reset, software reset's information is recorded position corresponding in the shared memory.Wherein, described software reset comprises: bios software resets and business software resets.That is to say, if resetting of business software generation then stored its repositioning information into first memory block; If resetting of bios software generation then stored its repositioning information into second memory block.
Can preserve following software reset's information: reset types, software type, reset time, status information.
Like this, behind the software reset, can obtain the repositioning information of this region memory storage when reruning this software.
Step 203: when device start, by BIOS judgment device reset types.
The state of the reset mode register that BIOS can provide according to device hardware is judged hard reset or warm reset.Then can obtain the information such as type of software by the repositioning information that writes down in the internal memory for warm reset.For hard reset, then can read in the reset mode register that hardware provides specifically is reset types such as electrification reset, hardware dog reset or push-button reset.
Step 204: revise software reset's information according to the device reset type.
Because BIOS can identification equipment reset types, if the software reset then can directly record repositioning information in the corresponding memory block; If hardware reset, the information that then can only write down the moment of startup once more is as hardware reset information, and this hardware reset information comprises: reset types, reset time, status information.Reset types is set to hardware reset when record, and be the time constantly that starts once more reset time.
Therefore, when reset types is hardware reset, remove the content of described first memory block, and hardware reset information is saved in described first memory block; Simultaneously, remove the content of described second memory block, and hardware reset information is saved in described second memory block.
Like this, in first memory block and second memory block, stored identical hardware reset information respectively, behind running software, just this information can be saved in respectively on the power down medium, such as, the hardware reset information of first memory block is saved in the zone of storage service software reset information on the power down medium, the hardware reset information of second memory block is saved in the zone of storage bios software repositioning information on the power down medium.Because resetting of hardware not only can influence the operation of business software, equally also can influence the operation of bios software, therefore, no matter can both inquire this hardware reset information when inquiry business software reset information or bios software repositioning information.
Step 205: when the business software of equipment moves, amended software reset's information is saved in power down keeps on the medium.Respectively the repositioning information of first memory block and the repositioning information of second memory block are saved on the power down maintenance medium.Power down keeps medium can use electricallyerasable ROM (EEROM), flash memory etc., can be on equipment veneer the storage chip of design specialized, also can with other same chips of information sharing that need power down to preserve, with simplified design, and reduce design cost.
In order to make present technique field personnel understand the present invention better, below in conjunction with the startup and the dissimilar preservation processes of repositioning information down that reset of operational process detailed description of equipment.
