Abstract

A fundamentally new type of RAMDAC¹ is described in which a custom digital signal processor (DSP) is interposed between the RAM and the DAC. The set of available colors is extended from 256 to over 700000 for an 8-b frame buffer. The device containing 60000 devices is fabricated in a 1.2-μm CMOS process supporting a 15-ns cycle operation.
