nanocobs VS libmorton

For packet framing take a look at COBS ( Consistent Overhead Byte Stuffing ). There are some good implementations on Github, I use this one.

I used it to accelerate nearest neighbor detection for collision processing in particle-laden flow for modeling complicated domains in 3d (for biological fluids simulation). I was using it a locality sensitive hashing to put particles near each other in the same bucket in an hash map. I came across the ideas of BIGMIN (big minimum) and LITMAX (little maximum) for range search in a morton encoded data that I found to be cool.

For example, I was able to accelerate ARM's vector-based arithmetic/logical bit-shifts into a single instruction compared to the 5 instructions it needed before thanks to AVX-512(also here's a little writeup I made on that). Or how I was able to accelerate ARM's vector bit-reversal into a just 2 fast instructions rather than the dozen that it needed before(another write-up I made on that). Or how using AVX512-BITALG can help accelerate interfacing with Morton Codes(common with encoding and decoding GPU texture formats).
