ABSTRACT:
A controller for controlling a one-sided switching matrix comprising a plurality of circuit elements under the control of logic circuitry. The controller interprets a request for connection or disconnection, determines if it is possible, selects a path through the matrix and sends control signals to the matrix. The circuit elements are arranged in a parallel/pipeline architecture with multiple circuit elements simultaneously operating on a request. The controller can fetch a second request while executing a first request. The result of a request is to connect or disconnect interconnection paths on the switching matrix.
