基于VxWorks 6.6系统的SATA控制器驱动技术研究

针对VxWorks 6.6操作系统下无法支持SATA接口的问题,提出了一种基于SATA控制器的驱动软件设计方法,该方法采用VxBus的驱动框架结构,支持AHCI模式、支持高速传输的NCQ技术,从而保证了SATA控制器功能的充分发挥.描述了基于SATA控制器驱动软件的主要设计思路和实现过程,该设计已经应用于嵌入式通信领域,并取得了良好的效果.

Research of SATA Controller Driver Based on VxWorks 6.6

For VxWorks 6.6 operating system cannot support SATA interface,We give a＇method of design with drivers on SATA controller.It adopts the drivers architecture of VxBus,which is supported by the mode of AHCI and the high speed transmission of NCQ.This article describes the main design idea based on SATA controller driver software and implementation process,which has been put into use,and performs stable in the application.
