+ * A reference C code of analysis filter with SIMD-friendly tables
+ * reordering and code layout. This code can be used to develop platform
+ * specific SIMD optimizations. Also it may be used as some kind of test
+ * for compiler autovectorization capabilities (who knows, if the compiler
+ * is very good at this stuff, hand optimized assembly may be not strictly
+ * needed for some platform).
+ *
+ * Note: It is also possible to make a simple variant of analysis filter,
+ * which needs only a single constants table without taking care about
+ * even/odd cases. This simple variant of filter can be implemented without
+ * input data permutation. The only thing that would be lost is the
+ * possibility to use pairwise SIMD multiplications. But for some simple
+ * CPU cores without SIMD extensions it can be useful. If anybody is
+ * interested in implementing such variant of a filter, sourcecode from
+ * bluez versions 4.26/4.27 can be used as a reference and the history of
+ * the changes in git repository done around that time may be worth checking.
