ABSTRACT:
The present invention provides efficient ways to implement scan conversion and matrix transpose operations using vector multiplex operations in a SIMD processor. The present method provides a very fast and flexible way to implement different scan conversions, such as zigzag conversion, and matrix transpose for 2×2, 4×4, 8×8 blocks commonly used by all video compression and decompression algorithms.
