Abstract: An all-analog natural language processing system is provided. Analog audio input is processed directly by an all-analog signal pathway wherein the audio activity detection, voice activity detection, feature extraction and neural network processing are all performed in the analog domain. Audio/voice detection and feature extraction is performed by a bandpass filter bank having a plurality of individual bandpass filters. Each bandpass filter includes an array of individual capacitively coupled current conveyor second order sections having a charge-trap transistor as a programmable element for tuning the passband of the filter. Compared to typical digital systems for natural language processing, the present all-analog system can perform natural language processing with comparable accuracy but greatly reduced energy consumption of up to two orders of magnitude less.

Abstract: The invention provides a method for utilizing the Inter Packet Gaps (IPGs) to create an Extended Link Monitoring Channel in a physical layer transceiver for a 10 Gb/s Ethernet link for communicating link related information, thus providing an extensive link maintenance capability. A corresponding transceiver between an Ethernet media access control (MAC) layer device and a 10 Gb/s Ethernet link, comprising a physical coding sublayer (PCS) extension circuit for implementing the Extended Link Monitoring Channel is also provided.
