摘要: A system comprising first input means for receiving a transport stream from an external source, second input means for receiving an input from a memory, means for connecting the first and second input means to an interface which is arranged to provide an output stream to a decoder. The second input means is arranged to provide an output to the interface in such a form that the interface does not distinguish between the output from the first and second input means.

摘要: Configurable adder circuitry is provided on an integrated circuit that includes redundant circuitry. The integrated circuit may contain nonvolatile memory and logic circuitry that produces a redundancy control signal. During manufacturing, the integrated circuitry may be tested. If a defect is identified on the integrated circuit, the redundancy control signal may be used in switching redundant circuitry into place bypassing the defect. The integrated circuit may contain an array of logic regions. Each logic region may contain adders and multiplexer circuitry for selectively combining the multiplexers to form larger adders. The multiplexer circuitry in each logic region may be controlled by propagate signals from the adders and by static redundancy control signals.

摘要: Circuits, methods, and apparatus for including interconnect parasitics without greatly increasing circuit simulation complexity and run times. Interconnect paths are reduced to one of a number of simplified topologies based on path width, length, or other parameters. The input drive waveform is similarly approximated. A grid array is formed in advance, where each point in the grid array corresponds to a set of values relating to a path topology, input waveform, and resulting output waveform. The simplified interconnect path and input waveform are mapped into a set of parameters which corresponds to a location in the predetermined grid array. The output waveform is determined by interpolating output waveforms from gridpoints surrounding the location.

摘要: A programmable logic device (PLD) includes a delay circuit and a body-bias generator. The delay circuit has a delay configured to represent a delay of user circuit implement in the PLD. The body-bias generator is configured to adjust the body bias of a transistor within the user circuit. The body-bias generator adjusts the body bias of the transistor in response to a level derived from the signal propagation delay of the delay circuit.
