Sigh, Firstly, getting from uncompressed at the input to compressed is basic processing. Seriously, you don't. Non risk instructions often take Multiple cycle

Sigh, Firstly, getting from uncompressed at the input to compressed is basic processing. Seriously, you don't. Non risk instructions often take Multiple cycles, so you can only do a tiny number of them between samples, usually just enough to compress it to fit the bus speed without loss. https://en.m.wikipedia.org/wiki/Cycles_per_instruction https://en.m.wikipedia.org/wiki/Cycles_per_instruction Thirdly, clearly you didn't rtfa. Fourthly, go disagree on the teensy forum. https://forum.pjrc.com/threads/27364-Teensy-3-1-and-ADC-FIR-Filtering https://forum.pjrc.com/threads/27364-Teensy-3-1-and-ADC-FIR-...
