A multimedia processing system is provided for communicating among a baseband module, an image sensor module, and at least one display module in a mobile phone. The system comprises: a serial baseband interface that transmits and receives processing data from the baseband module; an image sensor interface that transmits and receives image data from the image sensor module; a display interface that transmits and receives display data from the display module, wherein the display interface comprises a display write enable output, a display read enable output, and a display transceiver means to transmit and receive the display data; and at least one register that includes a clock phase control bit, a clock polarity control bit for assisting the serial baseband interface to accommodate different interface standards, and a burst read mode control bit for bursting the serial baseband interface to read sequential processing data from a multimedia module or from the baseband module.
