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)
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 _
How to use the NEON comparison instructions in general? Here is a case, I want to use, Greater-than-or-equal-to instruction?
Many SSE instructions allow th开发者_StackOverflow中文版e source operand to be a 16-byte aligned memory address. For example, the various (un)pack instructions. PUNCKLBW has the following signature:
I could not find any intrinsics for a simple xor operation. See: http开发者_运维技巧://gcc.gnu.org/onlinedocs/gcc/ARM-NEON-Intrinsics.html
Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers.
I\'m trying to figure out how to best pre-calculate some sin and cosine values, store them in aligned blocks, and then use them later for SSE calculations:
What are these data types for? __m64, __m128开发者_如何学Go, __m256 ?A quick google-search gives me:
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\'m involved in one of those challenges where you try to produce the smallest possible binary, so I\'m building my program without the C or C++ run-time libraries (RTL).I don\'t link to the DLL versi
