Abstract: A plurality of inputs are configured to receive circuit switched traffic from a plurality of initiators. A plurality of outputs are configured to output said traffic to a network on chip. Each output is associated with a different quality of service traffic. A traffic controller directs the received circuit switched traffic to respective ones of the outputs in dependence on a quality of service associated with the traffic.

Abstract: A converter circuit for performing transfer of control logic signals between a first device and a second device in connection with an interconnection bus, the first device operating at the frequency of a first clock signal and the second device operating at the frequency of a second clock signal. The clock frequencies may be in a first ratio to one another corresponding to unity, as well as in a second and a third ratio. The converter circuit includes manipulation circuit elements which define respective propagation paths through the converter circuit for control signals. A logic network may assume three states, corresponding, respectively, to the first, second and third ratios between the frequencies of the clock signals, selectively interposing the manipulation elements in the propagation paths.
