SIMD（Single Instruction, Multiple Data，单指令多数据）是一种并行计算技术架构，允许处理器在一条指令中同时对多个数据元素执行相同操作。其核心特征是利用向量寄存器批量处理数据，显著提升计算吞吐量。SIMD广泛应用于多媒体处理、科学计算、图形渲染及机器学习等对数据并行性要求较高的场景，是现代CPU和GPU硬件的重要组成部分。
C/C++ gives developers direct control over memory layout, cache friendliness, and SIMD vectorization
SIMD is a technique in modern CPUs that processes multiple data elements simultaneously with a single instruction
Core loops of matrix multiplication and convolution operations can achieve 4x to 16x throughput improvement when fully utilizing SIMD
