摘要： 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.

摘要： 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.
