摘　　要：介绍了基于FPGA的DSP开发技术,提出了一种设计正交信号发生器的方案。利用DSP Builder建立其数学模型,实现了模块化设计,使设计变得直观。在Simulink中进行仿真验证,通过Signal Compiler将模型转化成硬件描述语言,经过QuartusⅡ仿真正确后,下载到FPGA里。输出的正交信号能够灵活的调频、调相、调幅,实现了全数字化设计。该方案简化了硬件设计的难度,对各个模块的参数进行简单设置就能完成复杂的电子系统设计。The DSP development technology is introduced based on FPGA, and a plan for designing quadrature signal generator is proposed. The mathematical model is built with DSP Builder, the module design is realized, so that the design become intuition. The model is verified by simulation in Simulink, it is transformed into hardware description language through signal Compiler, which is downloaded to FPGA after Quartus Ⅱ simulation is correct. The output quadrature signal can realize flexible frequency change, phase change and amplitude change and realizes full digital design. Hardware design＇s difficulty is simplified using this plan, the complex electronic system design can be completed after each module＇s parameter is set up simply.
