SIMD (Single Instruction Multiple Data)即单指令流多数据流,是一种采用一个控制器来控制多个处理器,同时对一组数据(又称“数据向量”)中的每一个分别执行相同的操作从而实现空间上的并行性的技术。 简单来说就是一个指令能够同时处理多个数据。 如上图所示,使用标量运算一次只能对一对数据执行乘法操作,而采用SIMD乘法指令,则一次可以对四对数据同时执行乘法操作。 SIMD于20世纪70年代首次引用于 ILLIAC IV 大规模并行计算机上。 而大规模应用到消费级计算机则是在20实际90年代末。

In this article, we talked about the how SIMD works, history of SIMD specific to x86_64 architecture and demonstrated a practical example of how SIMD intrinsics can be used to improve
- Difference between SIMD and MIMD - GeeksforGeeks
The two basic classifications of parallel processing are SIMD which stands for Single Instruction Multiple Data and MIMD which stands for Multiple Instruction Multiple Data The use of SIMD enables the processing of many data with a single instruction and is applicable to most operations that are uniform such as image processing

SIMD (pronounced "sim-dee") is short for Single Instruction Multiple Data which is one classification of computer architectures SIMD allows one same operation to be performed on multiple data points resulting in data level parallelism and thus performance gains — for example, for 3D graphics and video processing, physics simulations or

This use of bitwise operations is often called "SIMD within a register (SWAR)" or "word-SIMD"; see Sean Anderson's "Bit Twiddling Hacks" for a variety of amazing examples But the most common form of SIMD today are the "multimedia" instruction set extensions in normal CPUs
