摘　　要：为了比较DSP和SOPC技术在电子设计领域的应用,采用泰勒展开法和DDFS技术,分别给出设计方案的硬件电路结构和软件流程图,并通过集成开发环境CCS和DE2开发板实现正弦信号发生器。结果表明,采用SOPC技术设计的正弦信号发生器与使用DSP芯片实现相比,其高速的运算能力以及内部操作的灵活性,使得产生的波形具有控制方便,输出相位连续,精度高,稳定性好等优点,具有很高的应用价值。In order to compare the application of Digital Signal Processor （DSP） and System on Programmable Chip （SOPC） technology in the field of electronic design,the schematics of the hardware circuits as well as the software flow chart of implementation schemes are respectively given by the method of Tailor progression and DDFS technology. The Sine signal generator is achieved by integrated development environment CCS and DE2 development board. The experimental result indicates that SOPC has much more high speed operational ability and flexible internal operation than DSP, and that the Sine signal generator designed by SOPC has better application value because it is characterized by convenient control, continuous output phase,high precision and good stability.
