Chapter 8
Optimization
On some versions of the serial port adapter there are some limited optimization
support regarding throughput, response time and power consumption.
Typically consider the following settings for the “Write_Link_Policy” command:
•
High throughput : Link policy 1 and 2 depending on which side is transmit-
ting and receiving. Note that this will only be useful to improve perform-
ance in one direction.
•
Short Response times : Link policy 3. Note that this will increase power
consumption. Link policy 4 may also be an option.
•
Low Power Consumption : Link policy 6-8. A longer sniff period will de-
crease power consumption more but provide longer response times. To
get even better results combine link policy 6-8 with stop mode.
Note that there is no guarantee that the configuration will improve performance
for a specific case. There may, for example, be some negotiation with the remote
device that forces some other parameters than the selected ones.
For best interoperability it is recommended to use the default link policy. For other
configurations make sure to test the specific application.
