SYSTEM ON CHIP FOR CONTROLLING POWER LINE COMMUNICATION

摘要

An SOC for controlling PLC is provided to enable an analog-to-digital converter, a DSP, a micro controller, and a plurality of communication interfaces to be on chip, thereby minimizing components and facilitating system design. A digital converter(110) acquires an analog signal generated in a device and converts the analog signal into a digital signal. A DSP(Digital Signal Processor)(120) processes digital data converted by the digital converter. Data processed through the DSP are transmitted through buses in a plurality of communication interfaces(130). A PLC(Power Line Communication) module(140) processes signals received by the DSP to be transmitted through a power line and transmits the processed signals to an analog interface or a communication interface. An analog interface(150) converts the digital signal into the analog signal to transmit the converted analog signal through the power line or converts the analog signal into the digital signal to transmit the digital signal to a PLC module. A micro controller(160) controls and manages the DSP and the PLC module.
