5.3.2.5 The Watchdog API
A watchdog timer (abbreviated as WDT) is a hardware device which
triggers an action, e.g. rebooting the system, if the system does not reset
the timer within a specific period of time. The WDT API in SUSI provides
developers with functions such as starting the timer, resetting the timer,
and setting the timeout value if the hardware requires customized
timeout values.
5.3.2.6 The Hardware Monitor API
The hardware monitor (abbreviated as HWM) is a system health
supervision capability achieved by placing certain I/O chips along with
sensors for inspecting the target of interests for certain condition
indexes, such as fan speed, temperature and voltage etc.
However, due to the inaccuracy among many commercially available
hardware monitoring chips, Advantech has developed a unique scheme
for hardware monitoring - achieved by using a dedicated
micro-processor with algorithms specifically designed for providing
accurate, real-time and reliable data content; helping protect your
system in a more reliable manner.
5.3.2.7 The Power Saving API
1. CPU Speed
– Make use of Intel SpeedStep technology to reduce power
consumption. The system will automatically adjust the CPU Speed
depending on system loading.
2. System Throttling
– Refers to a series of methods for reducing power consumption in
computers by lowering the clock frequency. APIs allow the user to
lower the clock from 87.5% to 12.5%.
