A pixel-parallel image processor using logic pitch-matched todynamic memory

摘要

A pixel-parallel image processor provides the capability forndesktop systems to perform low-level image processing tasks in realntime. Compact logic units are pitch-matched to DRAM columns to formndense blocks of processing elements. The processing elements areninterconnected to form a 64×64 array, with each processing elementnassigned to a single pixel. Operating with a 60-ns clock cycle in ancomplete system, fully functional devices dissipate 300 mW. Using thendevices, low-level image processing tasks have been performed in realntime with input images provided at rates exceeding 30 frames/s
