Skew lots for IC oscillators and other analog circuits
Integrated circuits, key components in thousands of products, frequently include thousands and even millions of microscopic transistors and other electrical components. Because of difficulties and costs of fabricating these circuits, circuit designers sometimes ask fabricators to produce skew lots for testing and predicting manufacturing yield. However, conventional skew lots for CMOS circuits, which are based on increasing or decreasing transistor transconductance, are not very useful in testing certain types of analog circuits, such as oscillators. Accordingly, the present inventors developed a new type of skew lot, based on increasing or decreasing gate-to-source capacitance of transistors, or more generally a transistor characteristic other than transconductance. This new type of skew lot is particularly suitable for simulating, testing, and/or making yield predictions for oscillators and other CMOS analog circuits. |

Efficient, robust file handle invalidation
The present invention provides a technique for efficiently generating and validating external file handles at a storage operating system of a filer. According to one aspect of the technique, the storage operating system associates a unique internal file handle with each file or directory stored in the filer. This unique internal file handle is used to generate a corresponding external file handle. Unlike previous approaches, the internal file handles' representations do not change depending on the location of their corresponding files or directories, e.g., on-disk or in-core, within the filer, thereby simplifying file management within the filer. According to another aspect of the inventive technique, the filer executes a file-handle validation procedure to determine whether an external file handle received with a file access request has become invalid (or “stale”) as a result of an NVRAM failure in the filer. The file-handle validation procedure enables the filer to efficiently determine the validity of the external file handle without having to perform conventional time-consuming and processing-intensive operations. Advantageously, the inventive technique is preferably only applied to generation and validation of external file handles configured in accordance with a stateless file-system protocol, such as the NFS protocol. In this way, there is no overhead added to the filer's storage operating system for generating and validating external file handles configured in accordance with stateful file-system protocols. |

Fast seek in streaming media
When a user selects to seek to a point in a non-indexed media file, a search starts for the beginning of the frame. Using a search algorithm, the bytes surrounding the selection point are examined to find data equal to a known frame beginning indicator. Once such a byte is found, a subsequent test is performed on the next byte to determine if it contains a valid frame length. The system examines the byte at this length to determine if it contains a value that points to the frame beginning indicator under examination. If such a pointer does exist, the system concludes that the byte with the value equal to a known frame beginning indicator is likely the byte beginning the frame. Additional tests may be performed on the bytes surrounding this frame to increase the confidence level that it is, in fact, a valid complete frame. |

Two stage frequency subband decomposition
A method for multifunctional processing of signals in frequency subbands performs subband decomposition and signal processing in two stages. A fullband signal is first splitted, with downsampling, into wide frequency subband (WFS) signals. Processing algorithms not requiring a high frequency resolution but benefiting from downsampling (such as subband acoustic echo cancellation), are applied to the WFS signals by wide subband processing blocks. Processed WFS signals are splitted, preferably without downsampling, into groups of narrow frequency subband (NFS) signals. The NFS signals are processed using processing algorithms (noise suppression, etc.) requiring a higher resolution. Processed NFS signals are synthesized into processed WFS signals, which are recombined into an output signal. Two-stage processing makes it possible to optimize signal processing, while keeping computational costs at low level and avoiding undesirable time delays. Preferred embodiments of the inventions are intended for use as an echo canceller/noise suppressor in voice communication terminals. |

Since only one operation on a queue is required for the typical case of several packets in a queue set rather than for every packet, the rate of queue operations may be significantly reduced. A queue set has a target data unit size, for example, a roughly equal number of packet bytes represented by each queue set, regardless of the number of packets referenced by a queue set. This means that a scheduler of a queue manager, which is tasked with metering the number of packet bytes transmitted from each queue per time unit, is provided with a list of packets which represents a predictable quantity of packet bytes, and this predictability streamlines the scheduling task and significantly reduces the number of operations. |

Network traffic control for virtual device interfaces
Processes for the control of traffic and Quality of Service (QoS) over a switch fabric network comprised of application servers and virtual I/O servers. In the embodiment, an application server includes virtual device interfaces, a QoS module, and a network port controlled by a packet scheduler. When the QoS module receives a packet from a virtual device interface, the QoS module stores the packet in a queue. The QoS module removes the packet from the queue and transmits it to the packet scheduler, in accordance with a hierarchical token bucket that allocates bandwidth for the port among the virtual device interfaces in the application server. In the embodiment, the port is the root of the hierarchy for the hierarchical token bucket and the virtual device interfaces are the leaves. The packet scheduler uses round-round arbitration to transmit the packet it receives to the port. |

Write splice for optical recording channels
An enhanced write splice for optical recording channels is disclosed. Optical control circuitry locks to previously-written data and determines the estimated write splice location. A training sequence is written to the optical medium at a location based on the estimated write splice location. The phase offset is then estimated by reading the training sequence. A new write splice location may then be calculated compensating for the phase offset estimate. Finally, the new data to be spliced may be written or overwritten to the channel at the new write splice location. |
