This tutorial surveys the present and future of multimedia computing systems and outlines new challenges for CAD presented by these systems. Multimedia computing is a challenging domain for several reasons: it requires both high computation rates and memory bandwidth; it is a multirate computing problem; and requires low-cost implementations for high-volume markets. As a result, the design of m...

Deep sub-micron VLSI technologies have led to a large increase in the number of devices per die as well as the switching speeds. These advances have been accompanied by increased design complexity and decreasing reliability. Scaling of the device dimensions has introduced “analog” effects on-chip that he causing signal integrity and delay problems. These problems are not easy to estimate and re...
