The method includes determining the center of gravity of the nacelle. Based on the center of gravity, a set of the plurality of yaw pads to be each substituted by a shim are selected. Each of the substituted shims including a thickness greater than the respective replaced yaw pad. The remaining yaw pads are replaced while the nacelle is supported by the shims.

Abstract: A decoder circuit includes an input to receive a first codeword encoded based on a quasi-cyclic low-density parity-check (QC LDPC) code. The first codeword includes a sequence of data arranged according to an order of columns in a first parity-check matrix associated with the QC LDPC code. A codeword reordering stage generates a reordered codeword by changing the sequence of the data in the first codeword based at least in part on a size of one or more circulant submatrices in the first parity-check matrix. An LDPC decoder generates a decoded codeword by decoding the reordered codeword based on a second parity-check matrix associated with the QC LDPC code. In some implementations, the second parity-check matrix may comprise a plurality of second circulant submatrices of a different size than the first circulant submatrices.

Abstract: Low-density parity check (LDPC) decoder circuitry is configured to decode an input codeword using a plurality of circulant matrices of a parity check matrix for an LDPC code. Multiple memory banks are configured to store elements of the input codeword. A memory circuit is configured for storage of an instruction sequence. Each instruction describes for one of the circulant matrices, a corresponding layer and column of the parity check matrix and a rotation. Each instruction includes packing factor bits having a value indicative of a number of instructions of the instruction sequence to be assembled in a bundle of instructions. A bundler circuit is configured to assemble the number of instructions from the memory circuit in a bundle. The bundler circuit specifies one or more no-operation codes (NOPs) in the bundle in response to the value of the packing factor bits and provides the bundle to the decoder circuitry.

Abstract: A decoder circuit includes a low-density parity-check (LDPC) repository to store parity-check information associated with one or more LDPC codes and an LDPC code configurator to receive a first LDPC configuration describing a parity-check matrix for a first LDPC code and to update the parity-check information in the LDPC repository to reflect the parity-check matrix for the first LDPC code. The decoder circuit further includes an LDPC decoder circuitry configurable, based on control signals, to perform LDPC decoding of codewords or LDPC encoding of information using the parity-check information from the LDPC repository.

Abstract: A decoder circuit includes an input to receive a first codeword encoded based on a quasi-cyclic low-density parity-check (QC LDPC) code and a plurality of memory banks to store the received codeword. Each column of the received codeword is assigned to one of the plurality of memory banks based at least in part on an order of the plurality of columns in the received codeword. A first reordering stage is to change the memory bank assignment for one or more of the plurality of columns by reordering the columns in the received codeword. An LDPC decoder is to decode the reordered codeword stored in the plurality of memory banks based at least in part on the QC LDPC code. A second reordering stage is to output the decoded codeword from the plurality of memory banks based at least in part on an order of the columns in the first codeword.

Abstract: A decoder circuit can include low-density parity-check (LDPC) decoder circuitry having a plurality of stages and an LDPC repository configured to store parity-check information associated with one or more LDPC codes. The LDPC repository is configured to determine a stall requirement for a layer of a first data block and perform a memory check for a second data block. The LDPC repository, in response to the stall requirement indicating a stall for the layer of the first data block and determining that the memory check is satisfied, is further configured to schedule processing of the first data block and the second data block in the LDPC decoder circuitry using the parity-check information by interleaving the layer of the first data block and a layer of the second data block through the plurality of stages of the LDPC decoder circuitry.

Abstract: An aspect of preemptive distribution of content includes monitoring content accessed in a local cache of a computing device. A time and a location of content accesses in the local cache are tracked. Prefetching heuristics are determined based on patterns of the time and the location of the content accesses. The prefetching heuristics are applied to speculatively prefetch additional content prior to the computing device receiving a request to access the additional content.

Abstract: A spectral response shifting method allows a listener to shift a system response to match their preferences. The method includes a lookup table of coefficients for a number of Infinite Impulse Response (IIR) filter or Finite Impulse Response (FIR) filter which are selected by the listener to shift the response either toward bass or towards treble. In one embodiment, 5th order IIR biquads filters are used at ½ dB increments from ?6 dB to +6 dB. For example, when a listener selects the “more treble by 1 dB” setting, a set of coefficients is loaded providing ?1 dB in bass cut at the lowest frequency of the audible spectrum (20 Hz) and +1 dB of treble boost at the highest frequency of the audible spectrum (20 kHz). The frequency response at all other points is defined by interpolating between the highest frequency (20 kHz) and the lowest frequency (20 Hz).
