Hi there. (Long time reader, first time poster. Yay!) I haven't done much with SIMD in the past, so my experience is pretty low, but my understanding is that each data piece must be defined prior to the operation, correct? Meaning that you can't use result of the operation of one piece of data as the source data for the next operation, right?
This came up in thinking about how to optimize an anti-aliasing routine. If, for example, the process is oversampling by 4 and running each through a low pass filter and then averaging the results, I was wondering if there's some way of using some SIMD process to speed this up, specifically the part sending each sample through the filter. Since each piece has to go through sequentially, I would need to use the result of the first filter tick as the input for the second filter tick. But that's not possible, right?
