Abstract:
An I/O interface supports scrambling, where the scrambling can include nonlinear scrambling of the scrambling code, or dynamic bus inversion of the scrambling code, or selective switching of selected bits of the scrambling code, or a combination of these. The transmitting device includes a scrambler and the receiving device includes a descrambler. Both the scrambler and the descrambler generate a linear feedback scrambling code modified by applying one or more of the techniques mentioned above. The modified scrambling code may cause fewer than half of the scrambled output bits to be toggled with respect to a previous scrambled output. The scrambler applies the modified scrambling code to a signal to transmit. The descrambler applies the modified scrambling code to a received signal.
Abstract:
An apparatus for generating a data signal comprises a processing circuit configured to generate the data signal, the data signal comprising a sequence of a first signal edge of a first type, a second signal edge of a second type, and a third signal edge of the first type, the first signal edge and the second signal edge being separated by a first time period corresponding to first data to be transmitted, and the second signal edge and the third signal edge being separated by a second time period corresponding to second data to be transmitted. An output interface circuit is configured to output the data signal.
Abstract:
Embodiments of the invention describe methods, apparatuses and systems for providing an efficient low power exit sequence for peripheral devices. In embodiments of the invention, a signal from a host device is transmitted to a SATA peripheral device for exiting a low-power state. An initialization time for OOB transmission and reception logic of the SATA peripheral device is tracked, and a reference time value based on the tracked initialization time is stored. In subsequent transitions from said low-power state, the reference time value for waking a host physical layer is utilized, thereby improving the efficiency of the management and use of said low power state. In some embodiments, the above described tracked initialization comprises a time from a transmission of an OOB signal (from the host to the peripheral device) to receiving an OOB response at the host device from the SATA peripheral device.
Abstract:
Provided are a computer readable storage media, method, and system for gathering sensed data from devices to manage host command transmission and cooling of the device. Host commands are retrieved from a host memory in a host to perform Input/Output operations with respect to a device. The retrieved host commands are transmitted to the device to perform the I/O operations of the host command. A monitor command is transmitted to obtain sensed data from the device while processing the host commands. A rate of transmitting the host commands is adjusted in response to determining that the sensed data received from the device in response to the monitor command satisfies a condition.

Apparatus, systems, and methods to manage memory latency operations are described. In one embodiment, an electronic device comprises a processor and a memory control logic to receive data from a remote memory device, store the data in a local cache memory, receive an error correction code indicator associated with the data, and implement a data management policy in response to the error correction code indicator. Other embodiments are also disclosed and claimed.

Abstract:
A hardware platform includes a nonvolatile storage device that can store system firmware as well as code for the primary operating system for the hardware platform. The hardware platform includes a controller that determines the hardware platform lacks functional firmware to boot the primary operating system from the storage device. The controller accesses a firmware image from an external interface that interfaces a device external to the hardware platform, where the external device is a firmware image source. The controller provisions the firmware from the external device to the storage device and initiates a boot sequence from the provisioned firmware.
Abstract:
A method and apparatus for entering a mode of a host controller and omitting a state of a state machine sequence of the host controller for data exchange by the host controller are disclosed. For one embodiment, the method and apparatus include setting a bit before a command information is transmitted to a separate device and exchanging data without sending the command information to the separate device. The bit of the embodiment indicates a current task file status.
Abstract:
A method, apparatus, system, and computer program product for enabling out-of-band access to storage devices through port-sharing hardware. Providing out-of-band access to storage devices enables system management functions to be performed when an operating system is non-functional as well as when the operating system is active. Storage commands originating with a management service can be interleaved with storage commands issued by the host operating system. The host operating system maintains ownership and control over its storage devices, but management activities can be performed while the host operating system is operational.
