Encoding apparatus, control method of encoding apparatus, and memory device

摘要

According to an embodiment, an encoding apparatus includes a parameter holding unit configured to hold a parameter; an error-detecting code holding unit configured to hold an error-detecting code that is generated from the parameter; an error detecting unit configured to detect an error in the parameter, which is held in the parameter holding unit, with the use of the error-detecting code held in the error-detecting code holding unit; an error correcting unit configured to correct the error detected by the error detecting unit; a selecting unit configured to select the parameter that has been subjected to error correction by the error correcting unit; and an encoding unit configured to encode data with the use of the parameter selected by the selecting unit.

1. An encoding apparatus, comprising:
an encoding unit configured to encode input data that is input from outside of the encoding apparatus and to output the encoded data to outside of the encoding apparatus; a parameter holding unit configured to hold a first characteristic parameter that is input from outside of the encoding apparatus; an error-detecting code holding unit configured to hold an error-detecting code that is generated from the first characteristic parameter; an error detecting unit configured to detect an error in a second characteristic parameter that is held in the parameter holding unit, with the use of the error-detecting code held in the error-detecting code holding unit; an error correcting unit configured to correct the error detected in the second characteristic parameter by the error detecting unit, thereby generating a third characteristic parameter; and a selecting unit configured to
select the third characteristic parameter when the error detecting unit detects the error in the second characteristic parameter, andselect the second characteristic parameter, when the error detecting unit detects no error in the second characteristic parameter, wherein the encoding unit encodes the input data by performing an encoding process with the use of a characteristic feature determined by a characteristic parameter that is selected by the selecting unit from among the second characteristic parameter and the third characteristic parameter and that is further input to the encoding unit.
