Unit Design And Implementation Of Fpga-based Large-scale Digital Exchange

This paper analyses the principle of the digital switching technology and describes the structure of Altera chips and its design software named MAX+PLUS II . On the basis of the above, it provides a detailed design of large digital switching units DX1000 based on the implementation of Altera FPGA. At last, It introduces the applications of DX1000 in the HJD04 switching system.
