CONNECTION NETWORK FOR ADJUSTABLE CIRCUIT CONNECTION, IN PARTICULAR PROGRAMMABLE CIRCUITS

摘要

Circuit arrangements (ULB) can be mutually connected by means of a connection network (VN). Each circuit arrangement (ULB) can operate as a transmitter or receiver. The connection network (VN) comprises a matrix composed of a connection matrix and an adjustment matrix. In the connection matrix the data transmission lines (DL) leading to the circuit arrangements (ULB) cross-over the coupling lines, whereby coupling elements are arranged at the cross-overs. The adjustment matrix consists of adjustment lines which cross-over the coupling lines, coupling elements being arranged at the cross-overs. By programming the coupling elements in the connection and adjustment matrixes and by applying an adjustment code to the adjustment matrix, it is possible to determine the connections between the data transmission lines. With the aid of control signals it is possible at the same time to determine whether the data transmission lines represent a data input or output.
