With considering unable- ending cycle in the process of practical use of embedded system, this article designs
three ways to avoid program going into unable—ending cycle by using software and hardware watchdog technology
when embedded system is disturbed.We analyses them in order to improve reliability and anti- jamming of the
system. Watchdog circuit is made up of the schism components in the SDI test system, improving the system ability
of anti- jamming and stability.
