摘　　要：在高清晰油气管道检测等应用场合,需要快速存储大量数据,使用传统的传输总线和Flash存储器已经难以满足要求,为了解决这个问题,本文介绍了一种应用于嵌入式系统中、基于SATA接口的高速大容量数据存储系统的设计。本设计基于高速SATA接口技术,以高速DSP为微控制器,以大容量电子盘为存储介质。本设计的存储速度可以达到32Mbit/s,存储容量高达120GByte,很好地解决了嵌入式检测系统中大量数据的快速存储问题。It＇s necessary to store a mass of data embedded systems, for example, high-resolution with hlgh-speed in many cases when using inspection system for oil ＆ gas transmission pipelines. Normal data bus and flash memory is difficult to meet the requirements, To solve the problem, this article introduces a design of data store system based on SATA connection, controlled by high speed DSP and using FlashDisk as store medium. The storage speed can reach 32 Mbit / s and storage capacity is up to 120 GByte. This design solves the problem of a large number of data fast storage in embedded systems very well.
