摘要
在SD存储卡设计讨论的基础上给出了实现过程,讨论开发平台。围绕提高速度设计和实现了系统架构,开发环境,基本模块设计和读写模块设计。通过这样的实现,可以使读写的速度达到20MB/s、12MB/s。通过W86L388D桥接芯片,控制器和Nand Flash芯片两块大的芯片实现SD卡硬件部分。通过四大模块来设计和实现控制器,保证最小的成本来实现高速度,满足工程对成本和速度的要求,达到了极高的安全要求。
Discussed in the SD memory card based on the design implementation process is given to discuss the development platform.Speed around the design and implementation of the system architecture,development environment,the basic module design,and the reader module design.Through this implementation,can read and write speeds of 20MB/s,12MB/s.By W86L388D bridge chip,controller,and two large Nand Flash chips SD card chip hardware.Through four modules designed and implemented the controller,guarantee a minimum cost to achieve high speed,cost and speed to meet project requirements,to achieve a high safety requirements.
