The the second reply data that there is volatile memory 13 rapidly return back to previous running status；If conversely, by electricity
Sub-device 10 is from normal mode of operation is switched to the program of standby mode, without positively by the above-mentioned second reply data
It is stored in volatile memory 13, or in stand-by mode, second, which replys data, is not preserved (example properly
Such as, electronic installation 10 causes the second reply Missing data by unexpected power-off or shutdown in the standby state), then after
In the continuous program that electronic installation 10 is switched back into normal mode of operation from standby mode, hardware core 12 will be unable to from easy
Read back the second reply data in the property lost memory 13.In this situation, hardware core 12 can perform the second operating system
Initialization program so that the second operating system is returned back into init state, so as to ensure that electronic installation 10 still can be just
Normal running.
In one embodiment, the first reply data being stored in volatile memory 13 have respectively with the second reply data
There is a data label.Hardware core 11 can search corresponding in volatile memory 13 respectively with hardware core 12
Data label reply data come first needed for obtaining and reply data with second.
In one embodiment, if electronic installation 10 has more hardware cores, carried out in electronic installation 10 standby
, all can be with for replying the reply data of running status for the operating system that each hardware core is run before pattern
It is stored in volatile memory 13.When the standby mode to be left of electronic installation 10 enters normal mode of operation,
