Last month a user posted some benchmarks on a STM32F4, which is a the
same core as your cc3220 but at 168MHz rather than 80Mhz. Here's the
results:

Based on that it seems that your decode should take about ~10ms, so
it'll be a bit of a squeeze to get full duplex in. But your numbers are
significantly worse. Are you running out of XIP flash? Do you have all
the flash accelerators and caches enabled?
