For integer loops, MMX(TM) technology and Streaming SIMD Extensions provide SIMD instructions for most arithmetic and logical operators on 32-bit, 16-bit, and 8-bit integer data types. Vectorization may proceed if the final precision of integer wrap-around arithmetic will be preserved. A 32-bit shift-right operator, for instance, is not vectorized if the final stored value is a 16-bit integer. Also, note that because the MMX(TM) instructions and Streaming SIMD Extensions instruction sets are not fully orthogonal (byte shifts, for instance, are not supported), not all integer operations can actually be vectorized.

For loops that operate on 32-bit single-precision and 64-bit double-precision floating-point numbers, the Streaming SIMD Extensions provide SIMD instructions for the arithmetic operators +, -, *, and /. Also, the Streaming SIMD Extensions provide SIMD instructions for the binary MIN, MAX, and unary SQRT operators. SIMD versions of several other mathematical operators (like the trigonometric functions SIN, COS, TAN) are supported in software in a vector mathematical run-time library that is provided with the Intel® C++ Compiler.
