Abstract :
A multicomputer-type parallel processing system has been developed that offers a peak performance of 12.8 GFLOPS. This system is called NOVI-II HiPIPE, and was designed for super-high-definition (SHD) image processing. SHD image is a new image medium and its resolution is higher than that of HDTV. Because SHD image processing requires computing power that exceeds the ability of any single digital signal processor (DSP), current or anticipated, NOVI-II HiPIPE uses a multicomputer-type parallel processing architecture. A 100-MFLOPS vector processor serves as the backend processor of each processing element. The current version of NOVI-II HiPIPE uses 128 mesh connected processing elements and 128 vector processors. The configuration and performance of NOVI-II HiPIPE are described
