摘　　要：信息技术的飞速发展对存储设备的存储容量、传输速率和稳定性等提出了更高的要求。为了满足多种设备之间高速传输的需求,高速串行大容量存储设备规范(SATA)接口作为主流存储设备接口,需要扩展。设计了一种SATA接口扩展电路,基于国产桥片搭建了外围电路及测试平台。详细介绍了硬件设计及测试方法,结果显示,下游5个SATA接口均能连接成功且传输速率均能达到6 Gbit/s,其他外设也均能正常读写。The rapid development of information technology has put forward higher requirements for storage capacity,transmission rate and stability of storage devices.In order to meet the demand for high-speed transmission between multiple devices,the high-speed serial advanced technology attachment(SATA)interface,as the mainstream storage device interface,needs to be expanded.A SATA interface expansion circuit is designed,and the peripheral circuit and test platform are built based on a domestic bridge chip.The hardware design and test method are introduced in detail,and the results show that all five downstream SATA interfaces can be connected successfully,the transmission rate can reach 6 Gbit/s,and the rest of the peripherals can also read and write normally.
