Abstract
A method may include generating a status signal, the status signal to indicate a status of Error-Locator-Polynomial (ELP) determination by an ELP determination circuit; and controlling the ELP determination by the ELP determination circuit at least partially responsive to a value of the status signal.
Claims22
An apparatus, comprising:
- an Error-Locator-Polynomial (ELP) determination circuit;
- and
- a logic circuit to set a status signal, the status signal to indicate a status of ELP determination by the ELP determination circuit,
- wherein the ELP determination circuit to:
- stop ELP determination at least partially responsive to a first value of the status signal;
- and
- continue ELP determination at least partially responsive to a second value of the status signal, wherein the second value different than the first value.
A method, comprising:
- generating a status signal, the status signal to indicate a status of Error-Locator-Polynomial (ELP) determination by an ELP determination circuit;
- and
- controlling the ELP determination by the ELP determination circuit at least partially responsive to a value of the status signal.
A decoder for Reed-Solomon decoding or Bose-Chaudhuri-Hocquenghem decoding, the decoder comprising an Error-Locator-Polynomial (ELP) determination circuit, the ELP determination circuit to exit an ELP determination at least partially responsive to an indication that a respective ELP reached a stable state.
