I\'m currently developing an OpenCL-application for a very heterogeneous set of computers (using JavaCL to be specific). In order to maximize performance I want to use a GPU if it\'s available otherwi
I have been working on SSE optimization for a video processing algorithm recently. I need to write the exactly same algorithm in C code to cross-check correctness of the algorithm. I forgot about this
One particular hot spot when I profile a code I am working on, is the following loop: for(int loc = start; loc<end; ++loc)
I have noticed that sometimes MSVC 2010 doesn\'t reorder SSE instructions at all. I thought I didn\'t have to care about instruction order inside my loop since the compiler handles that best, which do
I\'m having some trouble figuring out the NEON equivalence of a couple of Intel SSE operations. It seems that NEON is not capable to handle an entire Q register at once(128 bit value data type). I hav
There are 2 pointers to 2 unaligned 8 byte chunks to be loaded into an xmm register. If possible, using intrinsics. And if possible, without using an auxiliary register. Without pins开发者_开发问答rd.
My code is very simple for understanding SSE. My code is: #include <iostream> #include <iomanip&开发者_高级运维gt;
I am porting SSE SIMD code to use the 256 bit AVX extensions and cannot seem to find any instruction that will blend/shuffle/move the high 128 bits and the low 128 bits.
Does NEON support aliasing of the vector data types with their scalar components? E.g.(开发者_如何转开发Intel SSE)
Using the Accelerate framework from OSX, you get access to 4-way SIMD functionality where you can operate on vector floats, vector ints and vector bools. It gives you 4-way divisions e.g. and also 4-w
