Abstract: A method implemented to test a plurality of components coupled in a star configuration, each component having a test access port (TAP) controller. The method comprises performing a capture phase of a scan operation on all of the TAP controllers in the star configuration and sequentially selecting one of the TAP controllers at a time to perform a shift state. When all of the TAP controllers have been sequentially selected to perform the shift phase, the method further comprises selecting all of the TAP controllers to perform an update phase.

Abstract: A control circuit of a battery power-path management circuit establishes a first power path between a battery input node and an output node when the input node voltage is larger than a charger input node voltage and a second power path between the charger input node and the output node when the voltage on the charger input node is larger than the battery input node voltage. It controls the second power path to provide power to the output node, enabling battery charging and protection over a battery voltage range from about zero volts. It has low power consumption and can support wide-swing power supply voltage from as low as one volt to as high as maximum allowed Vds of drain-extended devices. It can use smaller device sizes because the PMOS switch gate voltage is 0V when the power supply is not too high.

A method of address assignment in a master/slave system, the system comprises at least one master, a plurality of slaves, and an I2C or I2C compatible bus. The method comprises sending a first address by the master on the I2C bus to a first of the plurality of slaves and storing the first address on the first slave to identify the first slave by the first address. The method further comprises sending a second address by the master on the I2C bus to a second of the plurality of slaves and storing the second address on the second slave to identify the second slave by the second address. The steps of sending and storing are repeated until all slaves of the system have stored an address.

Abstract: System and method for generating multiprimary signals with optimization for bit depth for use in display devices. A preferred embodiment comprises converting an input color signal into an output color signal, wherein the number of colors in the output color signal is less than a number of colors used in a display system, when a weighting of the input color signal is less than a specified threshold, and converting the input color signal into an output color signal, wherein the number of colors in the output color signal is equal to the number of colors used in the display system, when the weighting of the input color signal is greater than the specified threshold. The use of fewer colors eliminates low bit depth colors, allowing increased dither quality in dimmer images.

Abstract: A network element including a processor with logic for managing packet queues including a queue of free packet descriptors. Upon the transmission of a packet by a host application, the packet descriptor for the transmitted packet is added to the free packet descriptor queue. If the new free packet descriptor resides in on-chip memory, relative to queue manager logic, it is added to the head of the free packet descriptor queue; if the new free packet descriptor resides in external memory, it is added to the tail of the free packet descriptor queue. Upon a packet descriptor being requested to be associated with valid data to be added to an active packet queue, the queue manager logic pops the packet descriptor currently at the head of the free descriptor queue. Packet descriptors in on-chip memory are preferentially used relative to packet descriptors in external memory.

Abstract: A system and method for correcting optical distortion in an off-axis system is provided. The offset between the center of a display plane and the optical axis of the projection lens system is configured such that the offset is greater than half the vertical dimension of the display plane. In this manner, the distortion, such as a pincushion-type or barrel-type of distortion, is not symmetrical about the horizontal axis. In this scenario, the display plane, the projection lens system, a folding mirror, and/or the spatial light modulator may be tilted such that a keystone effect is induced. This keystone effect may be used to offset the distortion, particularly the pincushion-type or barrel-type of distortions.

The type of soft failures includes a failure during a read of a memory cell and a failure during the write of a memory cell.

Abstract: A novel mechanism for simultaneous multiple signal reception and transmission using frequency multiplexing and shared processing. Multiple RF signals, which may be of various wireless standards, are received using one or more shared processing blocks thereby significantly reducing chip space and power requirements. Shared components include local oscillators, analog to digital converters, digital RX processing and digital baseband processing. In operation, multiple RX front end circuits, one for each desired wireless signal, generate a plurality of IF signals that are frequency multiplexed and combined to create a single combined IF signal. The combined IF signal is processed by a shared processing block. Digital baseband processing is performed on each receive signal to generate respective data outputs. Further, simultaneous full-duplex transmission and reception is performed using a single local oscillator.

Abstract: A method of forming an IC including MOS transistors includes using a gate mask to form a first active gate feature having a line width W1 over an active area and a neighboring dummy feature having a line width 0.8 W1 to 1.3 W1. The neighboring dummy feature has a first side adjacent to the first active gate feature, and a nearest gate level feature on a second side opposite the first side. The neighboring dummy feature defines a gate pitch based on a distance to the first active gate feature or the neighboring dummy feature maintains a gate pitch in a gate array including the first active gate feature. The spacing between the neighboring dummy feature and the nearest gate level feature (i) maintains the gate pitch or (ii) provides a SRAF enabling distance that is ?2 times the gate pitch and the gate mask includes a SRAF over the SRAF distance.

Abstract: Packets of real-time information are sent with a source rate greater than zero kilobits per second, and a time or path or combined time/path diversity rate initially being zero kilobits per second. This results in a quality of service QoS, optionally measured at the sender or the receiver. When the QoS is on an unacceptable side of a threshold of acceptability, the sender sends diversity packets at an increased rate. Increasing the diversity rate while either reducing or maintaining the overall transmission rate is new. CELP-based multiple-description data partitioning sends the base or important information plus a subset of fixed excitation in one packet and sends the base or important information plus the complementary subset of fixed excitation in another packet. Reconstruction produces acceptable quality when only one of the two packets is received and better quality when both packets are received. Reconstruction provides for single and multiple lost packets.

Abstract: A system for processing a signal includes a detector configured to detect a two-level stream of bits; a converter configured to generate a three-level control signal based on two adjacent values within the two-level stream of bits; and a switch configured to determine which of three different paths to couple a current source to based on a value of the three-level control signal. Thus, based on adjacent values of the output stream a three-level control signal is generated which controls coupling of the current source to one of three different paths. This type of three-level digital-to-analog converter can be, for example, part of the feedback loop of an analog-to-digital converter. Similar techniques can also be utilized in a multi-segment digital-to-analog converter in which each segment of the DAC is controlled by a 3-level control signal and the DAC is implement using PMOS devices.
