The instruction set contains SIMD vector instructions which operate on multiple values contained in one large register at the same time.
2023/12/8 -Most commonly used contemporary CPUs support some SIMD instructions, which allow processing of multiple data by a single instruction.
2022/2/23 -This looks like a perfect candidate for SIMD but looking at the assembly in godbolt using gcc 11.2 -O3, it doesn't look like it uses SIMD instructions.
gcc has recently gained intrinsic support for some SIMD operations whereby the coder requests a vector of specified dimension and content, and then performs ...
2024/2/16 -The following code produces assembly that conditionally executes SIMD in GCC 12.3 when compiled with -O3. For completeness, the code always executes SIMD in ...

The most low-level way to use SIMD is to use the assembly vector instructions directly — they aren't different from their scalar equivalents at all — but we ...
2019/5/7 -std::experimental::simd is shipping with GCC since version 11. This package implements ISO/IEC TS 19570:2018 Section 9 "Data-Parallel Types".
2024/8/20 -An experimental implementation of the proposed SIMD library has been available in gcc since version 11. In this post we are going to explore the library and ...
2012/9/21 -Vector processing is in the category of Single Instruction, Multiple Data (SIMD). In SIMD, the same operation happens to all the data (the ...
