Yes, latency and jitter for anything running on the PRU will probably be in the uS time-scale. A typical real-time HAL processes running on the ARM core will have millisecond scale cycle rates with ~75 uS of jitter. So the PRU is definitely much faster, but it will probably require custom programming for your application The HAL solution could be implemented with existing HAL components, so no programming required (just HAL netlist wiring). -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
