Design of an USB2.0-ATA Bridge IP Core
USB2．0-ATA桥接器IP核设计

A series of portable mass storage devices are arising due to the effective support from USB2.0 interface. Mass storage Devices follow ATA protocol which is quite different from USB2.0 protocol, therefore a USB2.0-ATA bridge is needed to translate instructions and manage data between the two buses. This paper designs an IP core of USB2.0-ATA bridge, which can be easily used in development of USB devices with ATA interface embedded and SOC integrations.
