3 Summary

This application note provided a software-optimized method using PRU to increase FSI communication bandwidth and decrease the latency of data processing time. The verification results proved the effect of this method that the PRU handler helps to have six times reduction in FSI processing time (RX + TX) from 4.42 µs to 740 ns compares to R5 control. This can be useful for multi-axis servo control system.
