| Abstract: | The encoding and decoding circuit in hardware system of dual-network digital facsimile machine was designed.FPGA chip is adopted for the realization and validation of the system.The idea of two-stage coding and quick decoding was employed in the coding and decoding circuit of the system.The logical circuit was simplified with HDL design and simulation.The verification testing result shows that the circuit enhances the stability and reliability of the system,improves the encoding and decoding efficiency,and shortens the development cycle. |
