Doing my first peaces of SIMD to the audio pipeline :-) Both SSE and NEON.

Last time I did anything resembling this was when using FPU to divide 1/w while ALU is linearly interpolating the texture (on Pentium which has also nice and fast ALU pipeline, a leap over 486). This used to be common approach for software rendered perspective corrected texture mapping.

To get more texel throughput from Pentium, the next trick is to preprocess texture bitmap in 8x8 pixel tiles. That will significantly reduce cache misses :-)

For x86 I actually (after investigating) solely base on AVX2. There's no legacy history in this software so I don't care about legacy SIMDs (or want to implement them at least myself).
