Abstract
Systems and method relating generally to detecting information, and more particularly without limitation to systems and methods for synchronizing to a data stream.
Claims21
A data processing system, the data processing system comprising:
- a multi-format data processing circuit operable to process a data set including at least a first codeword encoded using a first encoding format and a second codeword encoded using a second encoding format, and wherein the multi-format data processing circuit includes:
- a data detection circuit operable to apply a symbol based data detection algorithm to symbols derived from the data set, wherein each symbol represents less than the number of bits in the first codeword and the number of bits in the second codeword.
A method for data processing, the method comprising:
- receiving a data input including at least a first codeword encoded using a first encoding format and a second codeword encoded using a second encoding format, wherein a length of the first codeword is different from a length of the second codeword;
- and
- applying a symbol based data detection algorithm to symbols derived from the data set, wherein each symbol represents less than the number of bits in the first codeword and the number of bits in the second codeword.
A storage device, the storage device comprising:
- a storage medium;
- a head assembly disposed in relation to the storage medium and operable to provide a sensed signal corresponding to a data set on the storage;
- a read channel circuit including:
- an analog front end circuit operable to provide an analog signal corresponding to the sensed signal, wherein the sensed signal includes at least a first codeword encoded using a first encoding format and a second codeword encoded using a second encoding format;
- an analog to digital converter circuit operable to sample the analog signal to yield a series of digital samples;
- a multi-format data processing circuit operable to process a data set derived from the digital samples, wherein the multi-format data processing circuit includes:
- a data detection circuit operable to apply a symbol based data detection algorithm to symbols derived from the data set, wherein each symbol represents less than the number of bits in the first codeword and the number of bits in the second codeword.
