That makes a lot of sense. Unfortunately, many things that make sense to me ultimately turn out to not be true. Does the definitive answer here lie with Gerald? I wonder if he (still) monitors this group... Regarding the PRUSS I have many questions. I'm really trying to nail down the

I'm working on using the PRU for critical signal timing, paired with userland code that loads data into the PRU local memory. I've done a lot of research learning about latency wrt local and system resources, L3/4 fabric delays, etc. In each case, I haven't seen any difference in the
