I\'m currently developing a C-module for a Java-application that needs some performance improvements (see Improving performance of network coding-encoding for a background). I\'ve tried to optimize th
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
Consider a single memory access (a single read or a single write, not read+write) SSE instruction on an x86 CPU. The instruction is accessing 16 bytes (128 bits) of memory and the accessed memory loca
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 currently working on an optimization of some C codes under MSVC, in which some sin() and cos() calculations are performed.
i\'m writing a small tool written in c and met on a segmentation fault which i don\'t know currently how to resolve. Running in GDB gives me the following hint:
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;
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)
