WebFor example, on the x86 the MMX, 3DNow! and SSE extensions can be used this way. The first step in using these extensions is to provide the necessary data types. This should be done using an appropriate typedef : typedef int v4si __attribute__ ( (vector_size (16))); The int type specifies the base type, while the attribute specifies the vector ...

WebThis is straightforward -- the intrinsics have made life really easy, as we simply access our memory using those (__m128i *) pointers, and the compiler sets it up so that the memory is loaded into 128-bit registers, the registers are used for 128-bit AND operations, and the results are stored back to memory. You can use __m128i data types as well if you want … Web我理解 mm shuffle ps如何工作的。 例如，在下面。 r將具有內容x ， x ， y ， y 。 但是我看到 MM SHUFFLE也為 mm shuffle ps 個參數，而矢量每個都有 個元素。 所以，邏輯上 MM SHUFFLE應該有 個參數。 有人可以解釋這是如何工作的嗎
