At least you can make SSE process four float streams in parallel without 
significant limitations to the algorithm itself. Getting all the 
benefits of SIMD with single stream would probably mean limitations or 
significant modifications to the algorithm.

Typically filter codes are something where compilers fail to generate 
fast code and where hand written asm usually helps. Complex math is 
another thing. I've seen this with FIR and especially IIR filters.
