Interface method and device in digital signal processing system

摘要

An interface method and device in a digital signal processing system which stores digital data regenerated from a recording unit in a memory, reads the digital data from the memory in response to a data transmission request signal of an object interface part, and transmits the read digital data to the object interface part in units of sound groups and also transmits channel classification data of 1 byte to classify the channel of the transmitted data together with the digital data to the object interface part.
