摘要： Source signals, such as audio and/or video data, are encoded into multiple, consecutive frequency bands. These bands are referred to as coding layers. Rather than performing complex bit-slice operations, a disclosed technique enables an agile and simplified response to transmission channel throughput variations. Specifically, if it becomes necessary to restrict the rate of data transmission to avoid receiver buffer underflow resulting from transmission channel degradation, layers from the transmitted signal are omitted, beginning with the highest frequency bands. Efficient and agile bit rate scalability during data streaming through wired or wireless networks and during local playback is thus enabled.
摘要翻译：诸如音频和/或视频数据的源信号被编码成多个连续的频带。这些频带被称为编码层。所公开的技术不是执行复杂的位片操作，而是能够对传输信道吞吐量变化进行敏捷和简化的响应。具体地，如果需要限制数据传输速率以避免由于传输信道恶化导致的接收机缓冲器下溢，则从最高频带开始，从发送信号中省去层。因此，通过有线或无线网络和本地播放期间的数据流传输期间，高效且敏捷的比特率可扩展性得以实现。

摘要： The automatic and optimal selection of coding parameter values according to analyses of coding trials is disclosed. The Neural Encoding Model (NEM) provides a method for providing a quantitative measure of the likelihood that a human observer can distinguish an original sensory signal from an approximation thereof, thus providing a metric by which the effect of various coding parameters may be analyzed and optimized. Optimal coding parameters can be defined for an entire data set, such as a digitized audio file, or for discrete portions of the data set. A trial coded data set or portion thereof is analyzed to determining if certain coding parameters have been assigned optimal values. If not, parameter manipulation is performed in an intelligent order and the objective analysis is repeated until predetermined objective perceptual distance criteria are achieved.

摘要： Round-off error in fixed-point arithmetic is minimized by changing the magnitudes of two multipliers simultaneously. The dynamic range of an intermediate output is thus maximized to increase computation precision. A much smaller round-off error, caused by fixed-point arithmetic, thus results.

摘要： A voltage generating circuit for generating internal voltage for a packaged integrated circuit memory device, is controllable to provide incremental adjustments in the voltage for testing of the memory device. The voltage generating circuit permits internally generated voltages of the memory device, such as the substrate voltage Vbb, the DVC2 voltage, and the pumped voltage Vccp, to be controlled externally through the application of test signals via the conventional test function, in performing standard device tests such as the static refresh test, logic 1s and 0s margin testing, and the like for packaged memory devices. Also, programmable circuits including programmable logic devices, such as anti-fuses, are provided that are programmable to maintain the voltage at a magnitude to which it is adjusted.

摘要： A synchronous semiconductor memory device has improved layout and circuitry so as to provide rapid operation. Data paths between sub-arrays and memory cells and corresponding DQ pads are equalized to provide approximately equal line delays, transmission losses, etc. Input clock circuitry converts a “asynchronous” external clock signal and external clock enable signal to an internal “synchronous” clock signal. Input command signals are not stored in input registers, but instead are latched so as to provide such input signals rapidly downstream. Multiple redundant compare circuitry is provided to improve delays inherent in selecting between external or internal addresses. Input/output pull up circuitry is enabled during both read and write operations, but shortened during write operations. Two or more voltage pump circuits are employed that permit sharing of power therebetween to compensate for increased power demands to row lines, data output lines, etc.

摘要： An integrated circuit memory device has a plurality of nonvolatile programmable elements which are used to store a pass/fail status bit at selected milestones in a test sequence. At selected points in the test process an element may be programmed to indicate that the device has passed the tests associated with the selected point in the process. Prior to performing further tests on the device, the element is read to verify that it passed previous tests in the test process. If the appropriate elements are not programmed, the device is rejected. A rejected device may be retested according to the previous test steps. Laser fuses, electrically programmable fuses or antifuses are used to store test results. The use of electrically writeable nonvolatile memory elements allows for programming of the elements after the device has been packaged.
