Abstract: Architecture and corresponding methods share resources and synchronize counters in high-speed network integrated circuits. The architecture has at least one counter group comprising several registers, each with two ports. One port receives networking events (e.g., receipt of an-error packet, transmission of a good packet, etc.) via a tri-state bus. The registers in each counter group use a shared hardware memory element, which adds the events for each counter group. The second port is available for asynchronous external read accesses via a second tri-state bus. The architecture synchronizes read requests with events such that read accesses occur during gaps in events. The registers are assigned to several mutually exclusive counter groups such that no two registers in the counter group increment in a basic clock cycle.

Abstract: A differential envelope detector for detecting the envelope of a received differential signal. The received differential signal comprises first and second received voltages, and the differential envelope detector provides a differential output voltage comprising first and second output voltages, where the difference of the first and second output voltages is indicative of the envelope of the difference of the first and second received voltages. For full-wave rectification, the first received voltage is coupled to the non-inverting input port of a first differential amplifier and the inverting input port of a second differential amplifier, and the second received voltage is coupled to the inverting input port of the first differential amplifier and the non-inverting input port of the second differential amplifier. The output ports of the differential amplifiers are coupled to their input ports to provide negative feedback.
