基于USB2.0的高速大容量数据采集存储系统
USB2.0 Based High Speed and High Capacity Sample Recording System
摘要
Abstract
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.关键词
