摘要： Provided are a method, system and program for effecting an operating system mode change from one mode to another. In one embodiment, the operating system in one mode is placed in a sleep state in which volatile memory remains active. In booting an operating system from the sleep state, a flag may be detected indicating an operating system mode transfer request. In response, contents of a selected range of volatile memory allocated to the first operating system mode may be swapped with the contents of a selected range of a reserve portion of volatile memory allocated to the second operating system mode. Booting of an operating system in the second mode may be completed using the swapped contents of the volatile memory. Additional embodiments are described and claimed.

摘要： A method and system to facilitate paging of one or more segments of a logical-to-physical (LTP) address mapping structure, such as a table, to a non-volatile memory, such as a NAND flash memory. The LTP address mapping structure is part of an indirection system map associated with the non-volatile memory. By allowing one or more segments of the LTP address mapping structure to be paged to the non-volatile memory, the amount of volatile memory required to store the LTP address mapping structure is reduced while maintaining the benefits of the LTP address mapping structure. One or more segments of the logical to physical address mapping structure may be cached in volatile memory, and a size of each segment may be the same as or a multiple of a page size of the NAND flash memory. A lookup or segment table may be provided to indicate a location of each segment and may be optimized for sequential physical addresses.
摘要翻译：一种有助于将诸如表的逻辑到物理（LTP）地址映射结构的一个或多个段的寻呼的方法和系统提供给诸如NAND闪存之类的非易失性存储器。 LTP地址映射结构是与非易失性存储器相关联的间接系统映射的一部分。通过允许LTP地址映射结构的一个或多个段被分页到非易失性存储器，减少存储LTP地址映射结构所需的易失性存储器的量，同时保持LTP地址映射结构的优点。逻辑到物理地址映射结构的一个或多个段可以被缓存在易失性存储器中，并且每个段的大小可以与NAND闪速存储器的页面大小相同或倍数。可以提供查找或分段表以指示每个分段的位置并且可以针对顺序物理地址进行优化。

摘要： Machine-readable media, methods, and apparatus are described to stream data between a codec and a buffer in system memory and to maintain a value in system memory that is indicative of a current position in the buffer. In some embodiments, an audio controller streams the data across an isochronous channel having relaxed ordering rules to the buffer in the system memory and updates the value indicative of current position via a write across the isochronous channel to the system memory.

摘要： A new audio playback architecture may be used, which allows the use of much larger buffering than that used by a typical audio subsystem in a computing system to improve power efficiency of the system and at the same time allows to maintain the quality (e.g., fidelity and responsiveness) of the audio playback. The audio controller in the new architecture may be made to report back to the host system a more accurate indication of which audio frame is being set to the audio codec than a currently available audio controller does. Additionally, the controller is capable of re-fetching previously buffered (but not yet transmitted) data. Furthermore, buffers in both the audio controller and the main memory may be dynamically adjusted during playback of audio data and/or for different applications.
