  • Publication number: 20090160485
    Abstract: An output block fabricated using a lower-voltage process provides output signals with a higher voltage swing. The output block contains a differential amplifier portion and a hold circuit portion. The differential amplifier portion is activated only when the logic level of an output signal needs to be switched. Once the logic level is switched, the hold circuit portion maintains the logic level. As a result, high switching speeds may be achieved with relatively low power consumption. The circuits of the output block are also designed so that no constituent components are subjected to excessive voltages, thereby providing enhanced reliability.

  • Publication number: 20090160523
    Abstract: An aspect of the present invention provides an input block which can receive input signals of a higher voltage swing when the internal components are fabricated using a lower voltage process. In an embodiment, the input block is designed to prevent current flow into an input signal path when the input signal is at a logic low level. In another embodiment, the input block is designed to recognize a logic value corresponding to a logic high level of input signals at a higher voltage level during a transition from logic low to logic high.

  • Patent number: 7530007
    Abstract: A receiver employs iterative decoding of packet data, where the packet data represents a data frame encoded with at least two logical dimensions. A logical dimension refers to a layer, or sub-layer, of a layered network architecture. Consequently, a first logical dimension of encoding might refer to error detection in a packet frame at the data link layer, while a second logical dimension of coding might refer to error detection/correction encoding at a physical layer. For example, a data frame might be divided into several packets, each with a corresponding cyclic redundancy check (CRC) value as coding in the first logical dimension, which are then transmitted with a convolutional code as coding in the second logical dimension. The receiver performs iterative decoding in the first and second logical dimensions until either i) all errors are identified and corrected or ii) another type of stopping condition is met.

  • Publication number: 20090103607
    Abstract: Systems and methods are described for providing a media stream transmitted from an encoding system to a remotely-located media player. The media stream is encoded according to an encoding parameter. Data is gathered about a transmit buffer within the encoding system, and the gathered data is processed to arrive at an estimate of network capacity and a calculated encoder rate. The encoding parameter is adjusted during subsequent encoding in response to a change in at least one of the estimate of network capacity and the calculated encoder rate.

  • Publication number: 20090083340
    Abstract: One embodiment of the present invention provides a system that facilitates merging different versions of a database object. During operation, the system receives metadata associated with a first version of a database object and a second version of the database object. The system then compares metadata associated with the first version with metadata associated with the second version to create a difference report. Next, the system uses the different report to create an action plan that specifies how to merge the metadata associated with the first and second versions of the metadata object.
