Leopard Sample Code: Performance
Current Intel and PowerPC processors include 128-bit vector engines to perform single-instruction multiple-data (SIMD) operations. These vector engines offer tremendous speed advantages, especially for highly parallel operations such as processing audio, graphics, or video. Developers can use these vector engines directly or take advantage of the functionality offered by the Accelerate framework.
