How can I replace the following 32-bit driver assembly to intrinsic as I am porting over my driver code to 64-bit:

Are there any Intel AVX intrinsics library out? I'm looking for something similar as 'sse2mmx.h' header which fall-backs to MMX intrinsics if SSE2 integer intrinsics are not available on compile time. Thus if I had similar library for AVX I could write optimized code for new hardware which would have…

Hi,
I wrote a simple program to implement SSE intrinsics for computing the inner product of two large (100000 or more elements) vectors. The program compares the execution time for both, inner product computed the conventional way and using intrinsics. Everything works out fine, until I insert (just…

Hello,
Is there any difference between logical SSE intrinsics for different types? For example if we take OR operation, there are three intrinsics: _mm_or_ps, _mm_or_pd and _mm_or_si128. My questions:
Is there any difference between using one or another intrinsic (with appropriate type casting)…

Hi all,
This is the first time I am posting a question on stackoverflow, so please try and overlook any errors I may have made in formatting my question/code. But please do point the same out to me so I may be more careful.
I was trying to write some simple intrinsics routines for the addition of…

I have an inline assembler loop that cumulatively adds elements from an int32 data array with MMX instructions. In particular, it uses the fact that the MMX registers can accommodate 16 int32s to calculate 16 different cumulative sums in parallel.
I would now like to convert this piece of code to…
