The Ivec classes provide an interface to single instruction, multiple data (SIMD) processing using integer vectors of various sizes. The class hierarchy is represented in the following figure.
Ivec Class Hierarchy
The M64 and M128 classes define the __m64 and __m128i data types from which the rest of the Ivec classes are derived. The first generation of child classes (the intermediate classes) are derived on element sizes of 128, 64, 32, 16, and 8 bits:
I128vec1, I64vec1, I64vec2, I32vec2, I32vec4, I16vec4, I16vec8, I8vec8, I8vec16
The second generation specify the signedness:
Is64vec2, Iu64vec2, Is32vec2, Iu32vec2, Is32vec4, Iu32vec4, Is16vec4, Iu16vec4, Is16vec8, Iu16vec8, Is8vec8, Iu8vec8, Is8vec16, Iu8vec16
Caution
Intermixing the M64 and M128 data types will result in unexpected behavior.
