Exercise 1: 熟悉 simd intrinsics 函数
WebC++ wrappers for SIMD intrinsics. Introduction. SIMD (Single Instruction, Multiple Data) is a feature of microprocessors that has been available for many years. SIMD instructions perform a single operation on a batch of values at once, and thus provide a way to significantly accelerate code execution. WebFeb 4, 2024 · 第一条指令是 add $1, -1 ,也就是计算 intrinsic function 的第一个参数减一后的结果,注意这条指令的作用是将 $1 != 0 的结果送入 carry flag; (第27085 行) 第二条 …
