摘要

This paper explores the key functions of AltiVec through an implementation of 2D IDCT algorithm. By providing a benchmark for video processing, the advantage of using SIMD-style of parallel processing technique has been demonstrated. Besides a variety of instructions available for parallel arithmetic computations, a solution for efficiently reorganising data for parallel processing is also provided by AltiVec. The implementation resulted in a speedup of 10 times compared to its scalar version.
