been doing more work on getting the code and system platform portable.
reading my own notes on things that have to be set like real time permissions.
good news is I have the 64 bit version also working on the Odroid C2, which means it will also work on the latest RPi.. Took a few naughty things to be fixed for AARCH64
CPU utilization is 40% on the C2 (4 x A53 @ 1,5G ) , same as XU4 (4 x
cortexA15 @ 1.4G + unused 4 x A7 ) which is surprising and good for power consumption, required grunt etc- for full 1500 Hz width of search window. Peak demod power consumption of about 2.5W.
