8.7 CPU Load Limits
As all microprocessors, the DDU 7’s processor has limited capacities. The current load of the
processor can be monitored using the channel “cpu_load”. When configuring your device,
please make sure the used CPU load is in a save range below 100 %.
Bosch recommends a maximum CPU load of 85 % (averaged). Exceeding this limit might result
in DDU 7 not being able to fulfill its required measuring/logging/display tasks or even in the
DDU 7 crashing and rebooting.
Main factors influencing the CPU load are:
–
Number and complexity of math channels
– Number and complexity of conditions
– CAN traffic on both CAN lines
– Display configuration, especially displaying pictures
– Logger configuration (total logging rate [kB/s], conditional measurement rates)
To help respecting the limit of 85 % CPU load, the DDU 7 creates an error memory entry. To
trigger this error entry, the CPU load must exceed the limit for 5 minutes without interruption.
When being confronted with this error memory entry (see ‘Error info’ in RaceCon) or when
being confronted with DDU 7 resets due to complex configuration setups, please consider
reducing the demands on the DDU 7 adapting the influencing factors mentioned above.
