I\'m trying to figure out how to set the \"mode\" flag for the _mm_cmpistrm SSE4.2 intrinsic. I have a regular C string (char*) that I am loading into an __m128i type with _mm_lddqu_si128. I was going
I am trying to optimize a small piece of code with SSE intrinsics (I am a complete beginner on the topic), but I am a little stuck on the use of conditionals.
I am trying to figure out a reasonably fast bilinear filtering function just for one filtered sample at a time now as an exercise in getting used to using intrinsics - up to SSE41 is fine.
Does anyone know how to remove all SSE2 intrinsics from sources (in Visual C++)? There are probably a few at some places, since I have been using SSE2. Now I\'d like to move my project to SSE again. I
I need to use _Interlocked*** function on char or short, but it takes long pointer as input. It seems that there is fu开发者_如何学编程nction _InterlockedExchange8, I don\'t see any documentation on t
Hi all :) I\'m trying to get a hang on a few concepts regarding floating point, SIMD/math intrinsics and the fast-math flag for gcc. More specifically, I\'m using MinGW with gcc v4.5.0 on a x86 cpu.
I\'m currently porting a Windows C++ library to MacOS as a hobby project as a learning experience. I stumbled across some code using the Win Interlocked* functions and thus I\'ve been trying to read u
Basic C++ class question: I have simple code currently that looks like something like this: typedef int sType;
I have just started learning and usingASP.NET MVC 2 and also getting more involved into unit testing my code. My question is broadly how to simulate a user log in by passing in credentials within my t
I am optimizing some code for an Intel x86 Nehalem micro-architecture using SSE intrinsics. A portion of my program computes 4 dot products and adds each result to the previous 开发者_C百科values in
