摘要
本SOPC系统在Altera公司Cyclone系列芯片EP1C6Q240中移植Nios Ⅱ嵌入式处理器,作为核心控制电路;利用FPGA丰富的可编程逻辑资源和IP软核构成嵌入式处理器的接口模块,实现对SDRAM存储器、FLASH存储器、LCD液晶显示器、独立键盘、LED等硬件的控制;软件设计采用开源的uC/OS-Ⅱ嵌入式实时操作系统,完成一个嵌入式系统硬件设计.经调试运行,在该系统上成功进行了推箱子游戏,验证了基于FPGA硬件设计的可行性,实现嵌入式实时多任务软件的开发.
In the system of SOPC,Nios Ⅱ embedded processor as the controlling core is embedded into a EP1C6Q240 of Altera Cyclone series.And the abundant programmable logical resources and IP core make up of the processor of peripheral interface controlling circuit,which provide SDRAM controlling,FLASH controlling,LCD display controlling,keyboard controlling,LED controlling,and so on.The system of the hardware design is realized and validated successfully by the result of testing that the game can play in the system and the software design of embedded multi-tasking operating system is realized,too.
