I'm not sure which Intel manuals you're looking at already.  A quick
bit of searching finds some that might be useful.

The Intel C/C++ compiler manual at least lists the available
intrinsics and gives some very brief introductory information.  Search
for "intrinsics" in the index:


Note: the compiler manual references an SSE2 "external architecture
specification" that does not seem to exist.

Here's a short introductory manual on using SSE and SSE2 (with both
intrinsics and inline assembly):


There's some specific examples here:


A short magazine article:


Some online tutorials with examples; the first one may require some
sort of registration process:


An introduction to SSE programming:


And of course there's the instruction set reference manuals, which I
think is where they've put the SSE stuff these days:
