摘要： Apparatus and methods for improved high-speed communication by exchanging low-speed information regarding the high-speed exchanges over the same communication medium. In one exemplary embodiment, a communication device includes a high-speed transceiver adapted to exchange high-speed data with another device via a communication medium using high-frequency signals. The device also includes a low-speed component adapted to exchange low-speed information over the same communication medium as low-frequency signals. The low-frequency signals may be applied as common mode signals to a differential communication path so as to not interfere with the high-speed data exchanges. In another embodiment, a high-pass filter may be included in the device to remove the low-frequency signals before the high-speed data is applied to the high-speed transceiver. Responsive to receipt of the low-speed information, a device may adjust parameters of the transceiver to improve the high-speed data exchanges.

摘要： Methods and systems for improving communication throughput of a link between SAS/SATA devices. The link, initially established at a first signal rate, is one of a SATA link and a SAS link. A SAS/SATA device increments one of the at least one counter based on an error sensed on the link. Based on the at least one counter, the SAS/SATA device determines whether to maintain the first signal rate. The link is re-established at a second signal rate based on the determination such that the second signal rate is lower than the first signal rate.

摘要： Methods and structure for directly coupling SATA hosts (SATA initiators) with SATA target devices through a SAS fabric and an enhanced SAS expander supporting such direct couplings. The enhanced SAS expander comprises SATA/STP connection logic to open a SAS (STP) connection between a directly attached SATA host and a SATA target device in response to receipt of an FIS from the host or target while no connection is presently open. The opened connection is closed after expiration of a predetermined timeout period of inactivity between the connected host and target. Thus, simpler, less costly SATA hosts and SATA target devices may be utilized while gaining the advantage of SAS architecture flexibility in configuration and scalability. SATA hosts may be coupled through the SAS fabric with a larger number of SATA target devices and multiple SATA hosts may be coupled with the SAS fabric.
摘要翻译：通过SAS架构和支持这种直接耦合的增强型SAS扩展器将SATA主机（SATA启动器）与SATA目标设备直接耦合的方法和结构。增强的SAS扩展器包括SATA / STP连接逻辑，以在直接连接的SATA主机和SATA目标设备之间打开SAS（STP）连接，以响应从主机或目标接收到FIS，而当前没有连接打开。打开的连接在连接的主机和目标之间的预定的不活动超时时间期满之后关闭。因此，可以利用更简单，更便宜的SATA主机和SATA目标设备，同时获得SAS架构在配置和可扩展性方面的灵活性的优势。 SATA主机可以通过SAS架构与更多数量的SATA目标设备耦合，并且多个SATA主机可以与SAS结构耦合。

摘要： Methods and structure described herein provide for detecting data inversions between electronic devices in communication with one another and automatically correcting those that inversions. An electronic device may be configured with a receiver that is configured for receiving differential serial data from a transmitter of another electronic device. The differential serial data is formatted according to a particular communication protocol associated with the electronic devices. The receiver detects an invalid sequence in the received differential serial data, such as an inverted SAS primitive, and automatically change the receive logic of the receiver such that subsequent received differential serial data is in the proper polarity. The transmitting device does not require notification of the change in receive logic.
