Difficult -- somehow your added comments are formatted as quoted text
(ie, my comments).

The PRU itself only runs at 200MHz, and you have to account for how
many instructions are needed to run your ADC-start, read, store, notify
host logic.

It uses Remote Proc for the examples -- but does NOT have ADC examples.
It does warn that Remote Proc/rpmsg is fairly new (at the time of the book)
and that things might change. Unfortunately TI has changed its document
access, so the links in the 2nd edition book don't work. Most of the
documentation seems to be at
http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components_PRU-ICSS_PRU_ICSSG.html#remoteproc-and-rpmsg
(note: processor SDK -- TI's raw OS build system).
The examples are the simple Blink LED until Button Pressed; a PWM
generator, Ultrasonic distance sensor.

On the BB AI -- and not much information has appeared on programming
them.
