Abstract

This nonvolatile 4-valued CAM is for fully parallel cellular logic image processing. Since gray-level or colored pixel values are directly represented by multiple-valued (MV) data in cellular logic image processing, a template-matching operation with an NxN window is performed by multiple-valued logic operations, that is ´universal literals´. Since many templates are required in some image processing, several templates are compressed. Universal literals are used to perform template-matching operations with MV compressed templates.
