Paper Abstract

This paper describes a new parallel image processing system called "NOVI-II HiPIPE" that manipulates super high definition (SHD) images. This system consists of 128 processing nodes, 4 I/O nodes for image storage, and 4 I/O nodes for SHD still image display. It provides extremely high computational power and high throughput rates for SHD image processing. This system can transfer image data to the newly developed Super Frame Memory (Super FM) for SHD moving image display via the Ultra-network. A new Vector Processor (VP), which has a peak performance of 100 MFlops, is developed and the performance of an engineering sample version of this chip is checked. One VP will be installed in each processing node as the DSP engine and a total system performance of 12.8 Gflops (peak performance) is expected from NOVI-II HiPIPE. Using this system, various image coding schemes and computer graphics techniques can be easily explored in spite of the huge amount of data that must be treated.
