摘要： A system and method of verifying data transferred along a data path from one buffer, such as a user buffer in the host system to a second buffer, such as a disc drive buffer on a disc drive system by using the receiving device to test the information and provide a confirmation or error signal to the sending device. The system and method appends non-abstract identification tags to the abstract data in the first buffer, i.e., the data to be stored to and/or read from the storage device. The tags are transmitted along with the abstract data and provide unique information that is used by either the disc drive device or the host system to validate data received from the other. The validation is based on a comparison of the tag values to a predetermined control value that may be received prior to receiving the abstract data.

摘要： In general, this disclosure describes techniques for implementing a system-wide reset of multiple devices. The techniques ensure that when any one of the devices of the system is reset, all the devices are reset. For example, a system includes a master reset device and a plurality of slave reset devices that are interconnected by a single reset line to provide improved robustness against electrostatic discharge (ESD) and electromagnetic pulse events. The master reset device detects a reset signal on the reset line and retransmits a true reset signal on the reset line in response to detecting the reset signal. Additionally, the master reset device may enter a blocking state after retransmitting the true reset signal to prevent detecting the reset signal that it transmitted on the reset line to avoid reset lockup.
摘要翻译：通常，本公开描述了用于实现多个设备的系统范围复位的技术。这些技术确保当系统的任何一个设备被复位时，所有的设备都被复位。例如，系统包括主复位装置和多个从复位装置，其通过单个复位线互连以提供抵抗静电放电（ESD）和电磁脉冲事件的改善的鲁棒性。主复位装置检测复位线路上的复位信号，并响应于检测到复位信号而在复位线路上重发真实复位信号。此外，主复位装置可以在重传真实复位信号之后进入阻塞状态，以防止检测其在复位线上发送的复位信号，以避免复位锁定。
