太神了……

因而你是说用 128 位寄存器一次 SIMD 四个 32 位数据?这事我想了很久,但因为加法会进位到相邻的值,我一直以为不可能。

ORIGINAL · 英文原文
That's amazing...

So are you saying you use 128-bit registers to SIMD four 32-bit data at once?  I've wondered about that for a long time, but I didn't think it would be possible due to addition carrying into the neighbour's value.
