CPU Utilization

The time required for the post-processing phase of the touch surface measurement cycle gives the CPU utilization for touch measurement. The CPU utilization for touch detection is typically expressed as a percentage of measurement periodicity. The table below shows the CPU utilization of the touch application (excluding the snake game functionality) in active and sleep modes with different measurement period values:

Table 1. Touch Surface Application CPU Utilization
Serial Number CPU State Measurement Periodicity in Active Mode Measurement Periodicity in Low-Power Sleep Mode CPU Load
1 Active 20 ms 64 ms 9%
2 Sleep 20 ms 64 ms 0%
3 Active 40 ms 64 ms 5%
4 Sleep 40 ms 64 ms 0%
