CODEC(4)은 DSP(1)가 녹음 또는 재생할 때 신호의 아날로그/디지털 변환 또는 디지털/아날로그 변환을 수행하고, 고체메모리카드(6)는 임의로 접속과 분리를 할 수 있는 탈착식으로, 압축된 오디오 정보를 저장한다. 슬롯(5)은 DSP(1)로부터 나온 어드레스버스(9)와 데이터버스(10), 제어신호버스(11) 등이 연결되어 있으며, 고체 메모리 카드는 특별한 명령에 의하여 데이터를 지우지 않는 한 슬롯에서 제거하였을 때도 데이터가 지워지지 않게 되어 있는 것으로, 이 기술은 일반적인 것이다.The DSP 1 is responsible for the control of the overall system as well as for data transmission and reproduction. The ROM 2 stores compression and decompression algorithms and entire system programs in storing and reproducing data. The RAM 3 stores temporary data during program execution. The CODEC (4) performs analog / digital conversion or digital / analog conversion of signals when the DSP (1) records or plays back, and the solid state memory card (6) is removable, compressed audio that can be arbitrarily connected and disconnected. Save the information. The slot 5 is connected to the address bus 9 from the DSP 1, the data bus 10, the control signal bus 11, and the like, and the solid state memory card is inserted into the slot unless the data is erased by a special command. This technique is common because data is not erased even when removed.
