    Present trends and future prospects are discussed, emphasizing the prospects for fuller VLSI integration of low-power digital radio, for applications such as in-building wireless radio receivers. The main concern is with the front end of the receiver, including continuous-time analog and sampled analog VLSI filtering, and technologies that can mix analog and digital on the same chip. Prospects for... View full abstract»

    The Viterbi algorithm (VA) is considered as an example of a fairly complex algorithm that needs to be implemented for high-speed applications. A brief introduction to the algorithm is given, and the state of the art of high-speed Viterbi decoders is reviewed. The three principal levels of introducing additional parallelism into an algorithm-bit level, word level, and algorithm level-are outlined, ... View full abstract»

    The demands imposed by large circuits on computer-aided design (CAD) systems are discussed, showing how each can be met. In particular, it is shown how a CAD system can handle many tools, accommodation different design environments, provide a flexible interface, provide user-specified constraints, and be platform independent. A complete system, called the Electric VLSI Design System which exhibits... View full abstract»
