Abstract: An configurable integrated-circuit device includes a plurality of regions that each contain electronic circuitry. The configurable integrated-circuit device also includes common circuitry adapted to provide at least one signal to at least two regions of the plurality of regions. The common circuitry and the at least two regions are positioned within the configurable integrated-circuit device so as to improve the latencies of the at least one signal to each of the at least two regions.

Abstract: A local area network is based on a ring of twisted pair cable links (UTP), each carrying at least 1.4 Mbps gross data rate. Each station on the network includes an encoder and a following station includes a decoder for PSK (phase shift keying) modulated serial data. The encoder uses an analog sine wave oscillator and inverter for generating antiphase analog sine wave signals at a carrier frequency and a switching circuit for selecting between the carrier signals according to the data signal to be transmitted. The decoder may use a simple integrator and comparator arrangement. The encoder and decoder may be provided in the form of an adapter circuit, such that a network based on optical fibre can be replaced by a network based on twisted pair cable using the same digital circuits. Generation of the PSK waveform by analog circuitry rather than digital synthesis reduces radio frequency emissions to a level suitable for use in an automotive audio/video communications network.
