I\'m writing a SSE code to 2-D convolution but SSE documentation is very sparse. I\'m calculating dot-product with _mm_dp_ps and using _mm_extract_ps 开发者_运维百科to get the dot-product result but _
I\'m very new to SIMD/SSE and I\'m trying to do some simple image filtering (blurring). The code below filters each pixel of a 8-bit gray bitmap with a simple [1 2 1] weighting in horizontal direction
Quick Summary: I have an array of 24-bit values.Any suggestion on how to quickly expand the individual 24-bit array elements into 32-bit elements?
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 com
I am trying to optimize some arithmetic by using the MMX and SSE instruction sets with inline assembly. However, I have been unable to find good references for 开发者_运维百科the timings and usages of
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 b
I\'m writing a highly parallel application that\'s multithreaded. I\'ve already got an SSE accelerated thr开发者_高级运维ead class written. If I were to write an MMX accelerated thread class, then run
I am curious, do new compilers use some extra features built into new CPUs such as MMX SSE,3DNow! and so?
I tried to follow: Project > Properties > Configuration Properties > C/C++ > Code Generation > Enable Enhanced Instruction Set
My Professor found out this interesting experiment of 3D Linearly separable Kernel Convolution using SSE and OpenMP, and gave the task to me to benchmark the statistics on our system. The author claim
