Abstract
A data encoder includes an encoding logic circuit configured to encode input data to apply run length limiting using state splitting of a code trellis, and a lookup table configured to apply a block-enumerable map on an un-split version of the code trellis, wherein entries in the lookup table are compressed.
Claims20
A data encoder comprising:
- an encoding logic circuit configured to encode input data to apply run length limiting using state splitting of a code trellis;
- and
- a lookup table configured to apply a block-enumerable map on an un-split version of the code trellis, wherein entries in the lookup table are compressed.
A method of encoding data, comprising:
- receiving input data to be encoded;
- performing state split-based encoding of the input data in an encoder circuit including retrieving compressed entries from a lookup table used in the state split-based encoding and reconstructing uncompressed entries based on the compressed entries to yield encoded data;
- and
- outputting the encoded data from the encoder circuit.
