Abstract: PURPOSE: An error correcting system is provided to realize a circuit to calculate an error position by a syndrome calculating circuit, thereby simplifying the circuit arrangement and the chip realization. CONSTITUTION: An error correcting system includes a data buffer(80) for storing received data, a syndrome and error position calculator(81) for calculating a syndrome in response to the received data and calculating an error position multinominal expression, an operation part(82) for calculating a coefficient of the error position multinominal expression and an error value, and an adder(85) for correcting an error calculated in the error position calculated in response to the output signal from the data buffer, an output signal from the syndrome and error position calculator and an output signal from the operation part.

Abstract: The circuit generates address signals necessary to correct errors in signals detected from an optical disk. The circuit includes a first counter for transmitting address signals equivalent to data symbols and parity symbols belonging to a same frame, a second counter for generating frame adress signals to designate address for symbols belonging to different frames, and an output stage for transmitting output signals of the counters to a memory.
Abstract translation: 该电路产生用于校正从光盘检测到的信号中的错误所必需的地址信号。 电路包括用于发送等同于属于同一帧的数据符号和奇偶校验符号的地址信号的第一计数器，用于生成帧地址信号以指定属于不同帧的符号的地址的第二计数器，以及用于发送属于不同帧的符号的输出信号的输出级 柜台到一个记忆。
