Nettet鑒於_mm256_sqrt_ps()相對較慢，並且我正在生成的值立即被_mm256_floor_ps()截斷，環顧四周似乎在這樣做： _mm256_mul_ps(_mm256_rsqrt_ps(eightFloats), eightFloats); 是獲得額外性能並避免流水線停滯的方法。 不幸的是，使用零值時，我當然會崩潰計算1/sqrt(0) 。 最好的辦法是什么？ NettetUsing Intel.com Search.

It uses … NettetThe __mm_set_ps and _mm_add_ps keywords are called intrinsics. SSE and AVX intrinsics all compile to a single assembler instruction; using these means that we are essentially writing assembler code directly in our program. There is an intrinsic for virtually every scalar operation: _mm_sub_ps( a4, b4 ); _mm_mul_ps( a4, b4 ); _mm_div_ps( … how to start a coroutine unity https://treyjewell.com
