20110170577 | High Speed Switch With Data Converter Physical Ports - A high-speed switch that includes a switch fabric, and both high-speed serial ports and data converter physical ports. A first set of data converter physical ports may perform analog-to-digital conversions, such that an external analog signal may be converted to a digital input signal on the switch. The converted digital input signal may then be routed through the switch fabric in accordance with a serial data protocol. A second set of data converter physical ports may perform digital-to-analog conversions, such that an internal digital signal received from the switch fabric may be converted to an analog output signal on the switch. The converted analog output signal may then be transmitted to an external destination in accordance with a serial data protocol. | 07-14-2011 |
20110170619 | High Speed Switch With Data Converter Physical Ports And Processing Unit - An integrated circuit chip implements a high-speed switch that includes: a switch fabric; control logic that controls the transmission of digital signals through the switch fabric; a transceiver block comprising one or more transceivers, each transmitting digital signals between the control logic and a corresponding external device; a data converter physical interface comprising one or more data converters, each performing a conversion between analog and digital signals, wherein digital signals associated with the one or more data converters are routed through the switch fabric; and a signal processing engine coupled to the control logic, wherein the signal processing engine performs on-chip processing of digital signals received from the transceiver block and the data converter physical interface. | 07-14-2011 |
20130198845 | MONITORING A WIRELESS NETWORK FOR A DISTRIBUTED DENIAL OF SERVICE ATTACK - An integrated circuit for monitoring a wireless network. The integrated circuit comprises a hardware interface configured to receive and access data packets transmitted over the wireless network; a programmable hardware accelerator configured to extract pertinent information from the data packets, the pertinent information for use in determining whether the wireless network is under a distributed denial of service (DDOS) attack; and a multi-core processor configured to receive the pertinent information and to determine whether the wireless network is under a DDOS attack based at least in part on the pertinent information provided by the programmable hardware. | 08-01-2013 |
20130307618 | LINEARIZING A POWER AMPLIFIER - A circuit for linearizing a power amplifier. The circuit includes a main signal path comprising a digital-to-analog converter, wherein a main signal is transmitted through the main signal path to said power amplifier; and a digital pre-distortion path disposed outside of the main signal path, wherein the digital pre-distortion path includes a digital pre-distorter for digitally pre-distorting the main signal. | 11-21-2013 |
