摘要
设计实现了以单片机AT89S51为控制核心,以现场可编程门阵列(Field Porgrammable Gate Array,简称FPGA)为数据处理核心,采用直接数字频率合成(DDS)技术构成的数字调制系统。各模块均通过Verilog HDL在FPGA上实现语言编程,经软件仿真和硬件测试验证均达到了设计要求。
The design of digital modulation system is based on the principle of direct digital frequency synthesis（DDS） ,using MCU （AT89S51） as a control core.The FPGA is taken as a core of data processing.All of the modules are realized in FPGA by means of Verilog HDL programming and found to meet to the design requirements through software simulation and hardware testing.
