Abstract: In a latch circuit having a bistable pair of cross connected transistors of a first polarity and a third transistor of a second polarity, a current signal greater than a bias current is received at a latch circuit port, amplified with the third transistor, and applied to the latch circuit port. This decreases the time in which the latch circuit port receiving the current signal greater than the bias current reaches a steady state voltage.

Abstract: According to one embodiment, a system for retaining M bits of state data of an integrated circuit during power down includes M serially coupled scan flip flops divided into M/N groups, where the M scan flip flops are able to save/restore the M bits of state data. Each group contains a merged scan flip flop coupled to a series of scan flip flops. The merged scan flip flop in each of the groups is coupled to a respective read port of a memory unit, and a final scan flip flop in each of the groups is coupled to a respective write port of the memory unit. The system enables the memory unit to save the M bits of state data in N clock cycles. Each merged scan flip flop has a read select input that enables restoring of the state data into the M scan flip flops in N clock cycles.

Abstract: LDPC (Low Density Parity Check) coded signal decoding using parallel and simultaneous bit node and check node processing. This novel approach to decoding of LDPC coded signals may be described as being LDPC bit-check parallel decoding. In some alternative embodiment, the approach to decoding LDPC coded signals may be modified to LDPC symbol-check parallel decoding or LDPC hybrid-check parallel decoding. A novel approach is presented by which the edge messages with respect to the bit nodes and the edge messages with respect to the check nodes may be updated simultaneously and in parallel to one another. Appropriately constructed executing orders direct the sequence of simultaneous operation of updating the edge messages at both nodes types (e.g., edge and check). For various types of LDPC coded signals, including parallel-block LDPC coded signals, this approach can perform decoding processing in almost half of the time as provided by previous decoding approaches.

The method continues by generating a transmit blocking indication based on the first protocol probable active time period and the first protocol probable inactive time period.

Abstract: Wireless local area network (WLAN) management. A novel approach is provided to associate various wireless stations (STAs) to the WLAN via appropriately selected Access Point (APs). In one implementation, a first AP services only those STAs that have functionality of a first user class (e.g., 802.11b functionality in one instance). In addition, a second AP services only those STAs that have functionality of a second user class (e.g., 802.11g functionality). The WLAN management ensures that STAs having similar characteristics (or similar functionality) are grouped together and associated with an AP that corresponds to those characteristics. For example, 802.11b STAs associate with the WLAN via an 802.11b AP. Analogously, 802.11g STAs associate with the WLAN via an 802.11g AP. When an 802.11g STA is unable to associate with the WLAN via an 802.11g AP, the STA may shift down its functionality set to 802.11b to successfully associate with the WLAN.

Abstract: A system and method for scheduling media for consumption via a demand broadcast channel based upon notifications received during user consumption of media. An embodiment of the present invention may employ notifications generated when users select media for consumption, to calculate one or more statistics. The statistics may be calculated and used by a media provider to schedule media into a demand broadcast channel in which the frequency of repetition or time of availability of the media is set according to a ranking of the relative frequency of requests for the media. The statistics may also be shared with a third party, to enable a third party media provider to arrange the scheduling of media availability according to the relative frequency of requests for the media.

Abstract: A system and method for over-voltage protection of a power amplifier is provided. A power amplifier is typically employed in a transmitter to amplify signals prior to transmission via a load; the load may include an antenna or a cable. As a result of an impedance mismatch between the power amplifier and its load, excess power from the power amplifier output fails to reach the load and must be dissipated by one or more transistors in the power amplifier. In severe impedance mismatch conditions, this dissipated power may damage or destroy the transistor(s). An automatic gain control (AGC) is provided for detecting a gain difference between the power amplifier and a replica power amplifier. A gain difference may signal an over-voltage situation. The AGC may be configured to adjust the gain of the power amplifier if a gain difference exists to prevent device damage.

Abstract: A high-quality, low-complexity audio time scale modification (TSM) algorithm useful in speeding up or slowing down the playback of an encoded audio signal without changing the pitch or timbre of the audio signal. The TSM algorithm uses a modified synchronized overlap-add (SOLA) algorithm that maintains a roughly constant computational complexity regardless of the TSM speed factor and that performs most of the required SOLA computation using decimated signals, thereby reducing computational complexity by approximately two orders of magnitude.

Abstract: Low power high-speed output driver. An array of switches (some of which are inverting switches whose connectivity is governed oppositely as the control signal provided to it) is implemented such that an input signal governs the connectivity of those switches. A resistor is coupled between the nodes interposed between the switches of the array, and an output signal is taken from the nodes at ends of the resistor. The high voltage level of such an output driver is truly the level of the power supply energizing the circuit (e.g., VDD) while still consuming relatively low power.

The address of this location is converted to a segment index. The segment index is stored in a sparse array.

Abstract: A system and method for measuring a cable resistance in a power over Ethernet (PoE) application. A short circuit module in a powered device is designed to produce a short circuit effect upon receipt of a cable resistance detection voltage.

Thereafter, one or more control commands are released based on a predetermined condition.

Abstract: A transmitter includes a detection element to determine when a current power requirement of a communication link is less than the standard transmit power. The current power requirement may be determined by a current operation condition of the communication link, for instance. The transmit power of the transmitter may be set to be less than the standard power in any of a variety of ways. For example, a center tap voltage of the transmitter may be reduced. In another example, a class of operation of the transmitter may be changed. In yet another example, the transmitter may include a current mirror having a plurality of diode-connected transistors coupled in parallel, thereby reducing the current at output terminals of the transmitter. Reducing the current at the output terminals decreases the output power of the transmitter, which may reduce the power consumed by the transmitter.
