  • Patent number: 10229072
    Abstract: The disclosure is directed to a system and method of managing memory resources in a communication channel. According to various embodiments, incoming memory slices associated with a plurality of data sectors are de-interleaved and transferred sequentially through a buffer to a decoder for further processing. To prevent buffer overflow or degraded decoder performance, the memory availability of the buffer is monitored, and transfers are suspended when the memory availability of the buffer is below a threshold buffer availability.
    Type: Grant

  • Patent number: 8976476
    Abstract: A hard disk drive or other storage device comprises a storage medium, a read/write head, and read channel circuitry coupled to the read/write head. The read channel circuitry comprises a despreader configured to generate a stitched logic sector by stitching together subsectors of that logic sector that were interleaved with subsectors of other logic sectors for storage on the storage medium, and a subsector bridging control module configured to control a number of bridging bits inserted by the despreader between a given pair of adjacent subsectors of the stitched logic sector. The subsector bridging control module may be illustratively configured to cause the despreader to insert a sufficient number of bridging bits between each pair of adjacent subsectors of the stitched logic sector so as to prevent discontinuities that might otherwise arise from use of X-averaging in generation of Y samples from X samples in a retry mode of operation.

  • Patent number: 6341024
    Abstract: A channel monitoring apparatus in a WDM system comprises: a plurality of tap couplers each for tapping a multiplexed optical signal at a predetermined percent at each monitoring point; an optical switch for selecting one of the monitoring points and optically switching an optical signal tapped by a relevant one of the tap couplers; an AWG module for dividing the optical signal switched by the switch by channels of the WDM system; a plurality of optical detectors for converting signals received from the AWG module into electric signals; a plurality of trans-impedance circuits for converting the electric signals converted by the detectors into voltage values proportional to current values of the signals; a channel multiplexer for selecting one of signals converted by the trans-impedance circuits; a fourth amplifier for amplifying the signal selected by the channel multiplexer; an analog/digital converter for converting the signal amplified by the fourth amplifier into a digital signal before applying it to a mi
