Other Parts Discussed in Thread: TMS570LS20216
In our upcoming project design we need to sample at 100 MHz two separate square input signals of between 7 kHz and 12 kHz, and to provide the free-running counters (10 ns per count) via IRQ to the CPU on either a rising or falling edge of its corresponding input signal. We've learned that the N2HET is capable of running at MAX 100 MHz to provide this functionality when using the HR resolution (our LR loop will be probably 8x instructions or 80 ns).
However, as we are not entirely certain about this TMS570 capability at this point of time, and by joggling its additional effects on aeronautical product certification, we would like to reach out to see whether TI manufactures some hardware counters that can lead us to a hardware solution.
Sorry if my request is a bit off-topic for this forum, but if a TI engineer can confirm that this is feasible with the TM570, it would be great.
