Abstract :
A 1.2-million transistor, 33-MHz, 20-b dictionary search processor (DISP) design that makes it practical to construct a 50000-word dictionary search system using only 20 DISPs is discussed. Special features of the DISP are (1) an architecture that drastically increases capacity of the content addressable memory (CAM), which handles high-speed character searches; (2) logic that increases the speed of the cellular automation processor (CAP), which conducts word searches; (3) architecture for reducing the size of CAP hardware. The fabrication technology employed was CD.8 mu m, 3-AI-level CMOS.<>
