I am using the following union declaration in SSE2. typedef unsigned long uli; typedef uli v4si __attribute__ ((vector_size(16)));
I have this function which uses SSE2 to add some values together it\'s supposed to add lhs and rhs together and store the result back into lhs:
I am trying to optimize a function using SSE2.I\'m wondering if I can prepare the data for my assembly code better than this way.My source data is a bunch of unsigned chars from pSrcData.I copy it to
I have the following bottleneck function. typedef unsigned char byte; void CompareArrays(const byte * p1S开发者_高级运维tart, const byte * p1End, const byte * p2, byte * p3)
My input data is 16-bit data, and I need to find a median of 3 values using SSE2 instruction set. If I have 3 16-bits input values A, B and C, I thought to do it like this:
I\'m very new to SSE and have optimized a section of code using intrinsics. I\'m pleased with the operation itself, but I\'m looking for a better way to write the result. The results end up in three _
I was reading today about researchers discovering that NVidia\'s Phys-X libraries use x87 FP vs. SSE2. Obviously this will be suboptimal for parallel datasets where speed trumps precision. However, th
In brief, I am trying to call into a shared library from python, more specifically, from numpy. The shared library is implemented in C using sse2 instructions. Enabling optimisation, i.e. building the
I\'m working on a bit of code and I\'m trying to optimize it as much as possible, basically get it running under a certain time limit.
I need to do determine processor support for SSE2 prior installing a software. From what I understand, I came up with this:
