| 摘要 |
Methods and arrangements to interface a data storage device such as a small form factor IDE/ATA hard drive are disclosed. Embodiments may comprise a host and/or a data storage device. The host and data storage device may form, e.g., a handheld device such as an MP3 player, a cellular phone, or the like. The host may comprise a new interface referred to as a CE-ATA interface that facilitates interaction with the data storage device. In many embodiments, the CE-ATA interface combines an ATA command layer or emulator with a Multimedia Card (MMC) electrical interface, advantageously accommodating a fast time-to-market solution by leveraging existing technologies. More specifically, ATA commands may be mapped into an MMC register space to transmit the commands to the data storage device. Several embodiments also implement interrupt functions for the data storage device. Other embodiments may be disclosed and claimed.
