example, to load 4 32-bit floats from memory to xmm (128 bit) register, we will use _mm_loadu_ps function. Figure 9. SSE intrinsic Similarly, to add 2 sets of 4-packed double precision floating point numbers present in ymm registers, we can use _mm256_add_pd function from AVX intrinsics. Figure 10.
