我正在为Knights Corner(KNC)cpu制作一个程序来执行 . 它似乎有一个AVX512的原型作为其指令集,但我没有发现英特尔内在指南在各种整数宽度之间的转换 .

具体来说,我'm trying to convert 8-bit integers (unsigned) into 32-bit integers so I can operate on them with KNC. How can I do this on KNC? Is there some equivalent to AVX512-F' s _mm512_cvtepu8_epi32() 从8位变为32位而 _mm512_cvtu[s]epi32_epi8() 从32位变回8位?
