Abstract

A fully parallel vector quantization (VQ) chip is applied to real-time compression of motion pictures due to its simple decoding algorithm. This processor chip minimizes clock cycles for a single VQ operation and has a versatile code book. In the VQ image compression algorithm, a micro-block of 4×4 pixels is approximated by the most similar pattern in the code book, and only the pattern code is transmitted. The receiver can retrieve the image by pasting corresponding patterns taken from the code book, enabling a simple decoding procedure in software. The VQ processor features and three competition stages all in parallel for vector matching search of the entire 2 k code-book vectors are also discussed.
