It is briefly described as follows the principle of the embodiment of the present invention.Value in the internal memory of electronic equipment is in such as hardware reset, soft
It can be preserved in the non-electrification reset of part reset etc, but if electronic equipment power down, then the value in the internal memory can lose.In electricity
After sub- equipment is re-powered, if the value not carried out actively to the internal memory in assignment, the internal memory is mess code.It is based on
This, from the interior verification base deposited verification variable in the presence of selection specific region and obtained according to the verification variable of electronic equipment
It is accurate；When the use process of electronic equipment resets, if performing verification to verification variable calculates obtained check results
Unequal with the calibration reference, then the value in explanation verification region turns into mess code due to power down, and the type of the reset is
Electrification reset；If the check results are equal with the calibration reference, the value in verification region is not mess code, the electronics
The type of reset in equipment is non-electrification reset (i.e. band reset).
The method for being used to determine electrification reset according to embodiments of the present invention is applied to any electronic equipment with internal memory,
The electronic equipment for example can be micro-control unit, digital signal processor, CPU, field programmable gate array electricity
Road etc., as long as it has internal memory.
The internal memory includes verification region, and the verification region is used to be stored in the calibration reference do not lost in non-electrification reset
With verification variable, the calibration reference is obtained by performing verification calculating to the verification variable.It should be noted that in described
The internal memory that can be internal memory in electronic equipment or be connected with the electronic equipment is deposited, it is, for example, that arbitrary access is deposited
Reservoir (RAM, Random Access Memory) internal memory.
As an example, for example selecting to open from the base address (that is, the address of the 0th byte) of internal memory in the internal memory of electronic equipment
128 bytes begun are used as the verification region.In addition, the start address of the internal memory is not limited to base address, it can be according to reality
