A fully-parallel vector quantization processor for real-time motion picture compression

Real-time compression of motion pictures is one of the most important technologies in multimedia. For personal and portable applications, efficient encoding/decoding algorithms that run fast on a simple hardware are in demand. Vector quantization (VQ) has a simple decoding algorithm. An extremely expensive computation required for encoding prevents its widespread use. A fully-parallel VQ processor chip for real-time encoding of motion pictures minimizes clock cycles for a single VQ operation and has a versatile code book.
