Abstract: In high-speed real-time signal processing systems are often used FPGA + DSP architecture .In accordance with their respective advantages, FPGA is often used as front-end signal processing and system control. This paper for specific projects, analysis of how to design IF orthogonal sampling (DDC) in FPGA implementation, how to achieve FPGA communication with the TS201 use link-port, and multiple real-time signal parallel processing in the FPGA to achieve.
Key words: Multi-channel; DDC; Real-time signal processing; link-port Communication; FPGA
