Because images sent from the .JERS-1 have very high resolution, their analyses require the power of a high-speed image processor. For this purpse, (.he ERSDIS, a celluEnr array processor based system, llas been adopted. The cellular array processor con~ists nT 4096 processing ~lements in a twwdirnensional array ant1 ii 's suital~le to process largescde image data at R high-speed. This paper describes the structure of the ERSDIS, and also the details of the cellular array processor unit used.
