I would assume he is using only one of the two cores, and still gets decode speed that looks just fine. For what that processor
costs, I'm not sure we /need/ anything slower.
I have the ESP32 running the server I wrote for Algoram Whitebox, and thus you can connect to it with your phone, tablet, or
laptop and control it using any HTML5 browser, using the phone mike and speaker. Or control your rig from anywhere in the world.
It is simultaneously a WiFi AP and client. I've not touched the Bluetooth code, but you can do that too. Pretty good for $5
ready to plug into your breadboard and $3.80 for the /module /(not just a chip) single quantity. I am using the native
programming interface rather than the Arduino one. But for people who have an Arduino code base, you can port it ESP32 and have
the network connectivity.
ESP32 and the associated IDE really knock it out of the park for
a connected device. Particularly nice they did necessary SMP
enhancements to the FreeRTOS scheduler and most of the IDE
libraries.
I haven't done any DSP on the ESP32; I've been too happy
with the Cortex-M4F core - particularly the STM32F4xx which
runs 0 wait-state.
