A MPEG encoder implementation on the Princeton Engine video supercomputer

The emergence of world wide standards for video compression has created a demand for design tools and simulation resources to support algorithm research and new product development. Because of the need for subjective study in the design of video compression algorithms it is essential that flexible yet computationally efficient tools be developed. The authors describe implementation of a programmable MPEG encoder on a massively parallel real-time image processing system. The system provides control over program attributes such as the size of the motion search window, buffer management and bit rate. Support is provided for real-time image acquisition and preprocessing from both analog and digital video sources (D1/D2)
