Abstract: The authors present a control scheme for UWModem with embedded processor in FPGA. The scheme builds system structure by choosing suitable communication bus type, and designs rational soft/ hardware cooperating procedure and interrupt controlling signals. The results from soft/hardware co-verification with MicroBlaze soft processor in Xilinx VirtexIV FPGA show that the control scheme can efficiently manager the whole digital signal processing in UWModem and report the situation in real-time with steady performance.
