Within the intel intrinsics guide, the pseudocode for the operation of _mm_insert_ps, the following is defined: . The access into imm8 confuses me: ...
Hey I have 3 integers with values max to 255 in xmm register. I want to cast them to bytes, and save them to memory. I dont know how to approach it. I ...
I am writing a textual packet analyzer for a protocol and in optimizing it I found that a great bottleneck is the find_first_not_of call. In essence, ...
I am running into an issue. After I compiled my program with no problem, then I ran it and got an error that I could not figure out: I did "nm -u 64 ...
Is there any way to perform a comparison like C >= (A + B) with SSE2/4.1 instructions considering 16 bit unsigned addition (_mm_add_epi16()) can ov ...
PCMPGTQ was introduced in sse4.2, and it provides a greater than signed comparison for 64 bit numbers that yields a mask. How does one support this f ...
I am trying to enable different simd support using MSVC. There is a page talking about enabling some simd, such as SSE2, AVX, AVX2 https://docs.micro ...
I know little much of assembly(NASM), i wanted to perform string operation(substring present or not) using SSE4.2. So i learnt how PCMPESTRI, PCMPISTR ...
I'm using the _mm_cmpgt_epi64 intrinsic to implement a 128-bit addition, and later a 256-bit one. Looking at the result of this intrinsic something pu ...
What I want to achieve is disabling SSE4.2 instruction set for CPU which VirtualBox emulated for my Linux guest OS for debugging purpose, even though ...
I am developing a hardware platform that requires the SSSE3 instruction set. When looking at a processor such as the Intel Atom® x5-Z8350 the datashee ...
So, one of the porpuses of docker is to easily deploy an environment to test software right? Can anybody tell me how to compile a Tensorflow binary to ...
Here is my code's assembler Can you embed it in c ++ and check against SSE4? At speed I would very much like to see how stepped into the development ...
I have written a library, where I use CMake for verifying the presence of headers for MMX, SSE, SSE2, SSE4, AVX, AVX2, and AVX-512. In addition to thi ...
I'm trying to write a strcmp version that takes advantage of SSE4.2 new instructions leveraging GCC intrinsics. This is the code I have so far: #inc ...
I have already installed tensorflow-gpu, and it is working fine. I now want to install tensorflow-gpu from source to take advantage of AVX and SSE4. ...
What can you do with SSE4.1 ptest other than testing if a single register is all-zero? Can you use a combination of SF and CF to test anything useful ...
I am trying to use some SSE4.2 intructions in string matching algorithms, coded in c++. I do not understand how to use these instructions to match s ...
I need to copy all the odd numbered bytes from one memory location to another. i.e. copy the first, third, fifth etc. Specifically I'm copying from th ...
