  • Patent number: 10296456
    Abstract: Tile based interleaving and de-interleaving of row-column interleaved data is described. In one example, the de-interleaving is divided into two memory transfer stages, the first from an on-chip memory to a DRAM and the second from the DRAM to an on-chip memory. Each stage operates on part of a row-column interleaved block of data and re-orders the data items, such that the output of the second stage comprises de-interleaved data. In the first stage, data items are read from the on-chip memory according to a non-linear sequence of memory read addresses and written to the DRAM. In the second stage, data items are read from the DRAM according to bursts of linear address sequences which make efficient use of the DRAM interface and written back to on-chip memory according to a non-linear sequence of memory write addresses.

  • Patent number: 10057048
    Abstract: A time-interleaved analog-to-digital converter (ADC) having M ADCs can increase the sampling speed several times compared to the sampling speed of just one ADC. Some time-interleaved ADCs randomize the order of the M ADCs sampling the analog input signal to improve dynamic performance. Randomization causes the output data of the M ADCs to be valid at randomized time instants. When the output data is sampled using a rising edge of a fixed clock, the output data can be valid just before, valid right at, or only valid for a short period of time after, the rising edge. Therefore, the setup or hold time can be very short. To address this issue, information regarding the randomized selection of an ADC is used to control the sampling occurring in the fixed clock domain and avoid the short setup or hold time.

  • Patent number: 10009132
    Abstract: Time stamp replication within wireless networks is described. In an embodiment, a wireless station receives an input time stamp and uses this input time stamp to generate an output time stamp. The wireless station transmits the output time stamp to wireless stations in one of a number of groups which make up the wireless network. The output time stamp is generated to compensate for delays between receiving the input time stamp and transmitting the output time stamp such that output time stamp which is transmitted at a time T corresponds to the value that the input time stamp would have had if it had been received at time T (and not at a time earlier than T). This may, therefore, reduce or eliminate independent time stamp errors and jitter caused by multiple disparate systems and processes.

  • Patent number: 9578397
    Abstract: Digital content encoded in a media file format may be presented by accessing the media file, reading parameters that describe the content, and processing the media file using the encoded parameters to “play” or generate output. Although the media file format may have multiple optional extensions, the media file generally includes one or more frames. Each frame may include a synchronized frame with the synchronized frame having a synchronized header, a video format indicator, an audio format indicator, a width indicator, a height indicator, a frame rate index, and a payload. Although the digital content may include different types and formats, the parameters used in the media file may be used to describe the digital content so that it may be processed independent of the underlying algorithm used. For example, multiple channels of audio signals may be described.

  • Patent number: 9397802
    Abstract: The present disclosure includes systems and techniques relating to wireless devices. A described technique includes generating respective frequency segments of a composite signal which are contiguous in a frequency domain, each of the respective frequency segments being based on a segment bandwidth; applying respective cyclic shift delay (CSD) phase shifts to the respective frequency segments to produce respective output signals; and transmitting the composite signal by transmitting signals that are based on the respective output signals. The respective CSD phase shifts, including first and second CSD phase shifts, are equivalent to third CSD phase shifts that correspond to a contiguous non-composite signal having a single frequency segment. A bandwidth of the single frequency segment is at least twice the segment bandwidth. The respective CSD phase shifts are applied such that a device receiving the composite signal uses the third CSD phase shifts that correspond to the contiguous non-composite signal.

  • Patent number: 9386558
    Abstract: The concepts relate to radio channel utilization and more specifically to determining whether individual radio channels are available for use. One example can obtain a signal on a radio channel. The example can identify that the signal is an occurrence of a licensed use when a power level exceeds a threshold. The example can also determine that the signal is not the occurrence of the licensed use when the power level of the signal and a phase of the signal do not match an expected power level and an expected phase of the occurrence of the licensed use.

  • Patent number: 9363555
    Abstract: There is provided a receiving apparatus including a position detection unit configured to detect a position at which same information as predetermined synchronous information is present from an acquired stream, and a boundary determination unit configured to determine positions at which the same information as the synchronous information detected by the position detection unit appears N times, where N>1, again and again in N cycles each of which is equal to a packet length, as a packet boundary position of the stream. The boundary determination unit determines the packet boundary position on the basis of a packet-boundary-position likelihood of the positions of the same information as the synchronous information in a case where the packet boundary position is unable to be uniquely located.

  • Patent number: 9356721
    Abstract: In a network device, apparatus and methods perform precision time stamping. A time agent receives a master pace signal corresponding to a time representation based on a master real time clock in a master clock domain. A time accumulator accumulates time units one fill quantum at a time based on the master pace signal. The time accumulator decreases the accumulated time units by a leak quantum according to a local clock signal running at a higher frequency than the master pace signal. Correction logic periodically generates, at a granularity corresponding to the frequency of the local clock signal, an updated time representation in a target clock domain based on a residual number of time units in the time accumulator before depositing an additional fill quantum of time units in the time accumulator.
