针对当前嵌入式采集系统中采用的寻址方式不能充分利用近几年出现的大容量硬盘所提供的存储空间,提出了一种基于USB2.0接口的高速大容量数据采集、存储系统的设计方案及其软硬件设计方法。文中设计的存储系统采用了ATAPI-6所定义的LBA48寻址方式,从而从根本上克服了LBA28寻址方式对存储空间的限制;采用UDMA传输方式,从而克服了传统PIO传输方式的速度瓶颈。研究表明此传输存储方案具有传输速度快、稳定性高、占用系统资源少、与外部接口简单等特点

As the addressing modes used in the current embeded acquisition system cannot make full use of storage space provided by the large capacity hard disk,a design scheme of a high-speed,high-capacity data acquisition and storage system and its design method of hardware and software is proposed,which is based USB2.0.This storage system adopts LBA48 addressing modes defined by ATAPI-6 and overcomes the restrictions in storage space caused by the addressing mode,LBA28.And this storage system adopts transfer mode,UDMA and overcomes the speed bottle-neck caused by traditional transfer mode,PIO.It is proved that this transmission storage scheme is high-speed,high-stability,taking up less system resources and having simple external interface
