Cost and Performance of VLSI Computing Structures

Abstract

Using VLSI technology, it will soon be possible to implement entire computing systems on one monolithic silicon chip. What will the nature of such systems be? How will they be designed? What will be their cost and performance? Conducting paths are required for communicating information throughout any integrated system. The length and organization of these communication paths places a lower bound on the area and time required for system operations. Optimal designs can be achieved in only a few of the many alternative structures. A random access memory is analyzed in detail as an example. It is shown that in each case an optimum design is possible, using the area - time product as a cost function.
