ZdNetItalia : OptiVec (16-bit)

Use vector functions instead of loops
OptiVec allows you to use vector functions instead of loops in your code, giving you faster and more accurate routines. OptiVec is entirely written in assembly language; the result is highly optimized and numerically accurate code that runs two to three times faster than compiled loops. Features include vectorized forms of all operators and functions of integer and floating-point data types, many other real and complex math functions, statistics, analysis, and FFT techniques. A 32-bit version is also available.
