    摘要： A method, system, and computer program product are provided for achieving timing closure in a clocked logic circuit. For each local clock buffer in a set of local clock buffers, a logic synthesis tool determines a clock control signal input from a set of clock control signal inputs that will drive a clock control signal to the local clock buffer at a target frequency such that a first timing constraint may be met. The operation performed by the logic synthesis tool forms a determined clock control signal input. Responsive to the logic synthesis tool determining the determined clock control signal input, the logic synthesis tool couples the local clock buffer to the determined clock control signal input that drives the clock control signal to the local clock buffer at the target frequency to achieve timing closure in the clocked logic circuit.

    摘要： A processing facility is provided for simultaneously receiving multiple streams of digital audio data and based thereon concurrently outputting both an unmixed digital audio signal and a mixed digital audio signal. The processing facility can be implemented, for example, within an audio decoder of a set top box. The facility includes receiving a first stream of digital audio data and a second stream of digital audio data, and outputting the first stream of digital audio data as an unmixed digital audio signal. Simultaneous therewith, the first stream of digital audio data and the second stream of digital audio data are digitally mixed and outputted as a mixed digital audio signal. If necessary, the second stream of digital audio data is redigitized based on a sample frequency of the first stream of digital audio data, and either or both the first stream and second stream of digital audio data are decoded prior to mixing.
