Title:
A METHOD OF MOBILE TERMINAL WITH DOUBLE PROCESSORS MORNITORING AND CONTROLLING THE WORKING STATUS PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2008/058435
Kind Code:
A1
Abstract:
A method of mobile terminal with double processors monitoring and controlling
working statue of slave processor is disclosed. A watch dog timer is started at
the side of main processor. A feeding dog process is included in function of process
of slave processor. In the period of the first predetermined time of the watch
dog timer, main processor sends reset signal to restart the slave processor if
main processor doesn't receive feeding. The solution can monitor the working
status of the slave processor by means of taking a timer in the main CPU as a watch
dog of slave CPU. When user can't know the status of the slave processor,
it can avoid the problem of dead cycle of slave CPU, or the problem of halting so
that it can improve the robust of the system.
