I would like to know, what is necessary to set in Visual Studio 2010, to have SSE 4.2 enabled? I would like to use it because of optimized POPCNT...
I\'m wondering why the following code with SSE2 instructions performs the multiplication slower than the standard C++ implementation.
I want to use a version of the well known MIT bitcount algorithm to count neighbors in Conway\'s game of life using SSE2 instructions.
I\'m sorting tuples of 16+16 bits as 32bit integers with SSE2. There are only signed integer instructions for compare and min/max. I don\'t have a problem with the order for the higher part as its jus
today I tried to initialize an array of the sse type __m128d. Unfortunately it didn\'t work - why? Is it generally impossible to create arrays of sse types (since they are register types?). The follow
I\'m trying to perform image colour conversion from YCbCr to BGRA (Don\'t ask about the A bit, such a headache).
I have a simple image processing related algorithm. Briefly, an image(mean) in float is subtracted by an 8-bit image
I\'ve just tried to optimize an RGB to YUV420 converter. Using a lookup table yielded a speed increase, as did using fixed point arithmetic. However I was expecting the real gains using SSE instructio
int u1, u2; unsigned long elm1[20], _mulpre[16][20], res1[40], res2[40]; 64 bits long res1, res2 initialized to zero.
The following loop is executed hundreds of times. elma and elmc are both unsigned long (64-bit) arrays, so is res1 and res2.
