9.5 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:
| 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% |
