摘　　要：介绍了NXP公司PowerQUICC II系列MPC8280处理器集成的SDRAM存储控制器的工作原理和工作模式,并在某国产化8280嵌入式系统开发板上,利用SDRAM存储控制器对4片SDRAM芯片进行读写操作。实际操作结果表明,该国产化8280处理器SDRAM存储控制器功能正常,可以访问SDRAM外设存储器。In the paper,the working principle and mode of the SDRAM storage controller integrated with NXP's PowerQUICC II series MPC8280 processor are introduced.On a domestic 8280 embedded system development board,use an SDRAM storage controller to read and write four SDRAM chips.The results of the paper indicate that the domestically produced 8280 processor SDRAM storage controller functions normally,can access SDRAM peripheral memory.
