CONTROLLER HAVING ERROR CORRECTION FUNCTION IN ACCORDANCE WITH OPERATING STATE OF MONITORING TARGET

摘要

A controller has an error correction capability by including: a state monitoring unit that analyzes a state of a monitoring target and outputs state information; an error correction processing unit that switches error correction codes so that a correction rate for the respective states becomes a value within a predetermined range; and a correction rate calculation unit that calculates the correction rate for the respective states based on the correction result by the error correction processing unit.

1. A controller that has an error correction function that encodes information data into code words and decodes code words into information data by using error correction codes, and automatically corrects a correctable error in decoding,
The controller comprising: a state monitoring unit that monitors a state of a monitoring target and outputs state information; a correction rate calculation unit that outputs a correction rate for respective states; and an error correction processing unit that has an error correction code group including a plurality of error correction codes having a correction capability ranking, which is defined based on a predetermined standard, encodes information data into code words and decodes code words into information data by switching the error correction codes, and outputs correction information related to the error correction, wherein the correction rate calculation unit is constituted to calculate the correction rate for the respective states based on the state information outputted by the state monitoring unit and the correction information outputted by the error correction processing unit, and the error correction processing unit is constructed to switch the error correction codes based on the correction rate for the respective states outputted by the correction rate calculation unit.
