The field of VLSI (Very Large Scale Integration) is concerned with the design, production, and use of highly complex integrated circuits. The research collected here comes from many disciplines, including computer architecture, computer-aided design, parallel algorithms, semiconductor technology, and testing. It extends to novel uses of the technology and concepts originally developed for integrated circuits, including integrated sensor arrays, digital photography, highly parallel computers, microactuators, neural networks, and a variety of special-purpose architectures and networks of special-purpose devices.
