摘要： One embodiment of the present invention provides a system that operatively couples an integrated circuit with a microstrip transmission line through chip lamination. The system includes a first semiconductor die containing the integrated circuit, and a second semiconductor die containing the microstrip transmission line. Unlike metal lines in the integrated circuit, which have relatively small cross-sections, the microstrip transmission line has a cross-section that is large enough so that signal propagation is governed by inductance and capacitance (LC) instead of resistance and capacitance (RC). The first semiconductor die and the second semiconductor die are laminated together so that the integrated circuit on the first semiconductor die is operatively coupled with the microstrip transmission line in the second semiconductor die.

摘要： Methods, systems, and computer programs are presented for managing a switching layer fabric. A network device operating system (ndOS) program includes program instructions for exchanging switching policy regarding a switching of network packets in a plurality of ndOS switching devices having respective ndOS programs executing therein. The first ndOS program is executed in a first ndOS switching device, and the switching policy is exchanged with other ndOS programs via multicast messages. Further, the ndOS program includes program instructions for exchanging resource control messages with the other ndOS switching devices to implement service level agreements in the switching layer fabric, where the ndOS switching devices cooperate to enforce the service level agreements. Further yet, the ndOS program includes program instructions for receiving changes to the switching policy, and program instructions for propagating the received changes to the switching policy via message exchange between the ndOS programs. The ndOS switching devices are managed as a single logical switch that spans the plurality of ndOS switching devices.

摘要： One networking device includes a switch module, a server, and a switch controller. The switch module has ports with a communications interface of a first type (CI1) and ports with a communications interface of a second type (CI2). The server, coupled to the switch module via a first CI2 coupling, includes a virtual CI1 driver, which provides a CI1 interface in the server, defined to exchange CI1 packets with the switch module via the first CI2 coupling. The virtual CI1 driver includes a first network device operating system (ndOS) program. The switch controller, in communication with the switch module via a second CI2 coupling, includes a second ndOS program controlling, in the switch module, a packet switching policy defining the switching of packets through the switch module or switch controller. The first and second ndOS programs exchange control messages to maintain a network policy for the switch fabric.

摘要： A repeater circuit, such as a clock regeneration and multiplication circuit, is described. In this repeater circuit, a clock multiplier unit (CMU) generates an internal clock signal based on a forwarded clock signal, which is received on a link. Furthermore, a phase interpolator (PI) in the repeater circuit provides the output clock signal based on the forwarded clock signal and the internal clock signal. Note that the CMU and the PI filter reduce the cycle-to-cycle jitter in the forwarded clock signal and the internal clock signal, and that the output clock signal has a phase that is a weighted average of the phases of the forwarded clock signal and the internal clock signal. In addition, the relative weights of the forwarded clock signal and the internal clock signal (i.e., the amount of phase averaging and jitter filtering) may be adjusted based on a position or location on the link.

摘要： A multiplying delay-locked loop (MDLL) is described. In the MDLL, a phase interpolator (PI) provides a correction signal to selection control logic by phase mixing two internal signals (which have different phases) from a sequence of delay elements in the MDLL. This correction signal compensates for a delay associated with the selection control logic, thereby ensuring that a selection pulse or signal output by the selection control logic to a selection circuit (such as a multiplexer) is appropriately timed so that the selection circuit can selectively injection lock the sequence of delay elements using edges in a reference signal.
