CPU and house majong circuit using AK3200M chip

Shown is the CPU and decoding circuitry using the AK3200M chip . The AK3200M realizes
all functions of the MP4 player with the cooperation of the peripheral circuits. The interface function of the chip can be
identified by the character mark of the interface circuit or the connection relationship of the external circuit. The main interfaces and functions are as follows:
    ● The video interface receives the video signal from the camera. The video signal passes through the A/D converter to convert the analog video into a digital video
    signal and then sends it to the chip for processing.
    ． The LCD display interface outputs data signals that drive the liquid crystal display so that images can be displayed on the LCD screen.
    ● The memory interface is used to connect to external memory to store data and programs.
    ● The clock circuit uses an external crystal to generate the clock signal required by the chip
.     ● Other interfaces are connected to peripheral circuits for data transmission, including USB interface, MMC/SD card interface, universal interface,
    power interface, etc.
