基于SOPC基本信号产生器的设计与实现

The Design and Realization of the Basic Signal Generator Based on SOPC

介绍一种基于SOPC的基本信号产生器的设计技术,以Altera公司EP1C6Q240C8为硬件核心,把软核CPU嵌入到FPGA之中构成片上系统(SOPC),并结合存储电路、高速DAC电路、LCD电路、键盘电路、JTAG配置电路以及电源电路等进行了硬件电路的设计,以此实现基本信号产生器。阐述了各主要模块设计方案,并给出软硬件测试图。通过示波器观察,满足了系统设计要求,达到预期目标。

This paper introduces a basic signal generator based on the SOPC design technology. In order to a- chieve the basic signal generator, the design of system hardware circuit takes EP1C6Q240C8of Altera Corporation as the hardware core, embeds the soft-core CPU into FPGA-chip, and unifies the memory circuit, high-speed DAC circuit, LCD circuit, the keyboard circuit, JTAG configuration circuit, the power circuit and so on. The paper describes the main module design and gives some pictures for hardware and software test. Through the oscilloscope observation, system design requirements are met and the desired objectives are achieved.
