An essential part of drones are the Electronic Speed Controller (ESC) which translate the commands from the flight computer into responses by the connected brushless motors (generally BLDCs). As the ESC determines a lot of the performance characteristics of a drone, it has its own firmware, which for (FPV) drones is overwhelmingly BLHeli, specifically...

With the performance of modern CPU cores plateauing recently, the main performance gains are with multiple cores and multithreaded applications. Typically, a fast GPU is only so mind-bogglingly quick because thousands of cores operate in parallel on the same set of tasks. So, it would seem prudent for our applications to try to code in a multithreaded...
