  • WIRELESS COMMUNICATION DEVICE AND METHOD FOR PROCESSING VOICE OVER INTERNET PROTOCOL SIGNALS THEREOF
    Publication number: 20070201431
    Abstract: A wireless communication device (10) for processing Voice over Internet Protocol signals includes an encoding and decoding module (30), a central processing unit (CPU) (20), a digital signal processor (DSP) (40), and a wireless communication module (50). The CPU communicates with the encoding and decoding module for controlling signal flows of the wireless communication device, and includes a multi-channel serial interface (MCSI) (200), an external memory interface (EMI) (210), and a serial peripheral interface (SPI) (220). The DSP communicates with the CPU via the MCSI and the EMI for compressing signals received from the MCSI and decompressing signals received from the EMI. The wireless communication module communicates with the CPU via the SPI for receiving and transmitting voice packets.
