摘要
SOPC是Altera公司提出的一种灵活、高效的片上系统解决方案,它将处理器、存储器、I/O等系统设计所需要的组件集成到一个PLD器件上,构成一个可编程的片上系统。NiosII是Altera公司推出的可以进行SOPC设计的处理器软核。文中提出了以FPGA为核心控制模块结合MAX125模数转换芯片,利用SOPC技术对FPGA进行设计,将NiosII软核处理器嵌入到FPGA中,并编译集成其它模块实现高速数据采集系统的设计方案对FPGA的程序进行仿真,对系统硬件测试结果进行分析,证明系统可以稳定可靠的运行。
SOPC is a flexible and efficient Soc design method developed by Altera Corporation. It could build a Soc design by integrating processor, memory, I/O and other peripherals into a PLD. NiosIl is a soft core microprocessor developed by Altera Corporation, which could be used to build a SOPC design. The scheme of a high speed data acquisition system which uses MAX125 A/D converter and FPGA as hard-core is introduced. The SOPC technology is used to design the program of FPGA in this paper. The NiosII, a soft-core microprocessor, is embedded in FPGA. Other modules are also compiled and integrated to implement data acquisition. The simulation figures of major FPGA modules and the analysis of the result of the hardware＇s test are provided in this paper. The data acquisition system is proved reliable and steady.
