Abstract
본 발명은 하나 이상의 비트가 손상된 메모리에 음성 데이터를 기록 및 독출하는 것이다.The present invention writes and reads speech data into a memory in which one or more bits are corrupted.
본 발명은 기록할 음성 데이터에 패리티 비트를 두어 메모리에 기록하고, 이를 독출하여 에러가 발생되었는지를 판별하며, 에러의 발생시 그 음성 데이터를 다음의 어드레스에 기록 및 독출하여 에러가 발생되는지를 판별하는 동작을 반복 수행하고, 에러가 발생되지 않았을 경우에는 다음의 음성 데이터를 다음의 어드레스에 따라 기록하고, 독출하여 에러가 발생되는지를 판별하는 동작을 반복 수행하면서 음성 데이터를 기록하며, 음성 데이터를 독출할 경우에는 독출된 음성 데이터에 에러가 발생되었는지를 판별하여 에러의 발생시 독출한 음성 데이터는 무시하고, 다음 어드레스의 음성 데이터를 독출하며, 에러가 발생되지 않았을 경우에는 독출한 음성 데이터를 출력한다.The present invention records parity bits in a voice data to be recorded, records them in a memory, reads them out, and determines whether an error has occurred. If the error is not repeated, if the error does not occur, the next voice data is recorded according to the following address, and the voice data is recorded while the operation of determining whether an error occurs by reading the voice data and the voice data is read. In case of an error, it is determined whether an error has occurred in the read voice data, disregarding the read voice data when an error occurs, and reads the voice data at the next address.
