SYSTEM FOR SAVING DIGITAL DATA

摘要

A digital signal processing device(2) reproduces record by a controller or a system control microcomputer(3). A memory interface(4) does buffering, driving, and speed buffering of data. A RAM(5) performs the 3rd error correction. A RAM controller(9) generates RAM address for reproduction and decoding. When recoding, it generates RAM address, for encoding and an interface part(14) stores ROM data received in the RAM(5) temporarily and when recording, sends encoding data to the memory interface(4), when reproducing, receives reproduction data from a ROM interface and sends it to a ROM for decoding.
