Abstract
In response to the current problems of short lifespan and high cost in storage devices,we chose to use the domestic microcon-troller GD32 to reduce the cost,and adopted the equalization loss algorithm to extend the memory lifespan,and designed a high-capacity data storage system.The system takes GD32 as the control core,with two pieces of NAND Flash as the storage media,connected through the EXMC interface that comes with GD32,and uses two RS422 to communicate with the host computer for data:one way to transmit the storage data,and the other for the command control.The host computer manages the storage status and controls the wear and tear of the NAND Flash block through the balanced loss algorithm.After testing,the system reaches a storage capacity of 32 GB,and a writing speed of 1 MB/s.The service life of NAND Flash is improved,ensuring stable performance and meeting the requirements for long-term,high-capacity data storage.关键词
