摘要： A method for measuring perceptual quality of voice signals, audio signals, audio-video signals, and multimedia signals in communication equipment in an operational embodiment communicates a processed test signal via a network from a first device to a second device. The processed test signal is then received by an equipment under test, which further processes the processed test signal to recover a representation of the test signal. The recovered test signal is then objectively analyzed to determine a measure of perceptual quality by comparing the recovered test signal to a pre-stored representation of the test signal. A quality measurement unit that conveniently attaches to equipment under test identifies and evaluates quality of recovered test signals communicated from a remote device, or a test signal communicated by the equipment under test. In the latter case, the quality measurement unit communicates with both the equipment under test and with the network, so that the quality measurement unit itself receives a representation of the communicated test signal by the equipment under test.

摘要： A distributed processing system having a host processor including a host communication infrastructure (HCI) configured for communication with said host processor; a plurality of class processors each having an associated private localized read/write memory; and a plurality of application program interface modules each configured to provide an interface between said host communication infrastructure and at least one said class processor, wherein each said class processor responds to selected data messages on said HCI to perform selected computations utilizing said read/write memory. This embodiment provides an ideal architecture for fabrication on a single chip and avoids processor and bus bottlenecks by providing distributed processing power with local memory for each class processor.Also provided is a method for designing a distributed processing system for an application. The method includes steps of partitioning the application into functions and data messages; configuring a host processor having a host communication infrastructure (HCI) to pass data messages via the HCI to control the application; configuring a plurality of class processors to compute the functions into which the application is partitioned in response to the data messages; and interconnecting the class processors to the host processor via application program interface modules in a star configuration. Systems designed in accordance with this method embodiment are well-suited for integration on a single chip, and can be easily updated and modified as necessary, because changes made to a class processor have minimal effect on the remainder of the system.

摘要： A method for providing real-time perceptual quality measurements of an audio signal (12) in which a quality test signal, including an audio test signal, is received by equipment under test. Playback of a pre-stored representation of the audio signal is coarsely synchronized (20) to the received audio test signal, for example, utilizing a synchronizing pulse in a header of the quality test signal. The playback is then finely synchronized (24) to the received audio signal, for example, by comparing data in a windowed portion of the received audio test signal and a windowed portion of the pre-stored representation of the audio test signal and by adjusting a windowed portion of the pre-stored representation of the audio test signal in accordance with results of the comparison. A window of the received audio test singal is then compared (14) to a portion of the finely synchronized play back of the pre-stored representation of the audio test signal to output a quality measurement of the received audio test signal.
