Desired frequency :
The desired frequency is the frequency that the EV Driver will try to reach when displaying video
stream on a PMD device.
This parameter is very important for performance : effective display frequency and CPU
consumption. For this reason, the user should take care in choosing the correct value for this
parameter, depending on their needs.
The best way to choose a correct value is to analyze the performance of the EV Driver. This can be
done by checking the information group box when the driver is running (see 4.3.2.) :
–
if the user asks for a desired frequency which is greater than the current measured
frequency, the driver can reach this desired frequency. Consequently, the effective
measured frequency will be approximately equal to the desired frequency, and the CPU
usage will not be too high. For example :
–
If the user asks for a desired frequency which is less than the current measured frequency,
the driver will probably not reach this desired frequency. As a result, the effective frequency
will be lesser than expected, and the CPU usage may be high.
