PURPOSE: An embedded IP phone installing an EISC(Extendable Instruction Set Computer)-based SIP(Session Initiation Protocol) protocol is provided to improve the speed and performance of the embedded IP phone by mounting an EISC-based MCU(Micro Controller Unit) and installing the SIP communication protocol. CONSTITUTION: If a system is initialized, all execution codes stored in a flash RAM are copied to a DRAM and the entire procedure is executed through the DRAM. An Ethernet module performs communication among several terminals in an IP Ethernet. The Ethernet module uses an EISC-based MCU embedding an Ethernet controller. A physical layer chip is connected between the Ethernet controller of the MCU and an RJ45 for transmitting an Ethernet packet to a network through the RJ45. The EISC-based MCU performs a bidirectional communication between IP terminals through an SIP communication protocol installed in the system, and transmits a network packet including voice digital data generated in a DSP(Digital Signal Processor) through the Ethernet module to be capable of voice communication.

CONSTITUTION: If an image capture receives an analog image, the analog image is converted into the digital data by an Analog/Digital converter. The digital data is sent to an LCD screen by an LCD controller. The data compressed by a TIFF(Tagged Image File Format) JPEG(Joint Photograph Exchange Group) according to a video codec is stored and transferred to other device by the USB(Universal Serial Bus), the UART(Universal Asynchronous Receiver/Transmitter), and the Blue-tooth. All controls are performed by the SE3280 EISC core.
