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.

DETAILED DESCRIPTION Accordingly, it is an object of this invention to provide an electronic controller for a cross-point switch with minimum delay.
It is a further object of this invention to provide a controller that can simultaneously process multiple service requests.
The invention may be briefly summarized as a controller for a cross-point switch comprising a plurality of electronic elements arranged in a parallel/pipeline architecture.
The pipeline characteristic allows one step of a first request to be serviced simultaneously with another step of a second request.
The parallel characteristic within segments of the pipeline allow several sub-steps of a step to be performed concurrently, thereby reducing the delay in servicing the request.
