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.

Abstract: The disclosure is directed to a system and method for storing and processing check-node unit (CNU) messages utilizing random access memory (RAM). A decoder includes a layered array of CNUs configured to receive at least one variable-node unit (VNU) message associated with decoded bits of at least one data segment being operated upon by the decoder. The decoder further includes a CNU message converter configured to permutate at least one initial circulant of the VNU message to generate a converted CNU message having sub-circulants sized for RAM-based processing. The decoder further includes RAM configured to store sub-circulants of the converted CNU message at addressable memory blocks for parallel VNU processing.
