    using instruction set extensions vs. not using them

    Hello,
    I am wondering wether you compression algorithm programmers are using any instruction set extensions (like MMX, SSE, AVX, whatever). So it would be nice, if you already did some programming in this area, to participate in the poll and thereby tell what your decision was.

    I bet you could find out by searching this forum, using terms like avx and sse. I find it's easier to get useful results by using google with the modifier "site:encode.su" than through the built-in search.

    Sometimes it is good, sometimes it is not. It all depends on your project's goals. You've noted the main tradeoffs already. However, I don't see how is it supposed to reduce code size.
