ABSTRACT:
A read port for selectively coupling one of a plurality of inputs to an output is disclosed. The read port comprises: a plurality of inputs; an output; a plurality of multiplexers operable to selectively couple a selected input to said output; and a multiplexer control signal input for inputting a multiplexer control signal, the multiplexer control signal comprising a plurality of control parameters and being operable to control switching of the plurality of multiplexers. The plurality of multiplexers are arranged in a plurality of layers, the layers being arranged between the inputs and output, such that a selected input is operable to be coupled to the output via a multiplexer from each of the different layers. Furthermore, some of the layers are divided into portions, each portion having at least one control parameter input, so that each of the portions is operable to be controlled by a different one of the control parameters and multiplexers in one of the portions of a certain layers can be switched without switching multiplexers in another of the portions this layer. In some embodiments two outputs operable as two read ports are provided.
