摘要： Methods, apparatuses, systems, and storage media for creating, discovering, and/or resolving spells using a wand are provided. In embodiments, a computing device or a wand may detect one or more gestures and sensors in the wand may generate sensor data representative of the one or more gestures. The one or more gestures may be movements performed using the wand. The computing device or wand may convert the sensor data representative of the one or more gestures into a spell sequence. The wand may transmit the spell sequence to a computing device, and receive, from the computing device, a spell output based on the spell sequence and a wand position. The wand may also determine the spell output based on the spell sequence without transmitting the spell sequence to another device. Other embodiments may be described and/or claimed.

摘要： Method and apparatus for content protection using one-way buffers. In one embodiment, the method includes storage of content decrypted by a host processor within a reserved range of memory. In one embodiment, a peripheral device requires the host processor to decrypt the received content for playback by the peripheral device. The decrypted content is stored within a reserved range of memory that is not accessible by malicious software. Hence, content is transferred from the reserved range of memory to a device driver of the peripheral device. In one embodiment, access to the reserved range of memory consists of write-only access by the host processor and read-only access by the peripheral device. In one embodiment, prior to storage of the content within the reserved range of memory, the content is re-encrypted prior to storage and decryption prior to transfer to the peripheral device. Other embodiments are described and claimed.

摘要： An apparatus and method for unilaterally loading a secure operating system within a multiprocessor environment are described. The method includes disregarding a received load secure region instruction when a currently active load secure region operation is detected. Otherwise, a memory protection element is directed, in response to the received load secure region instruction, to form a secure memory environment. Once directed, unauthorized read/write access to one or more protected memory regions are prohibited. Finally, a cryptographic hash value of the one or more protected memory regions is stored within a digest information repository as a secure software identification value. Once stored, outside agents may request access to a digitally signed software identification value to establish security verification of secure software within the secure memory environment.

摘要： A method and apparatus is described for computing a duration of a reduced power consumption state. A time of exiting from the reduced power consumption state is read prior to an execution of an interrupt routine. The read time of exiting is then stored in a register and a calculation of a reduced power consumption state duration may be performed.

摘要： An integrated circuit device, such as a processor initiates a transition to a first power management state. The device then receives a request to exit the first power management state and, in response exits the first power management state at the highest of a reference operating voltage, such as a minimum operating voltage, and a current voltage. For one aspect, an analog to digital converter may be used to determine the current voltage level. Further, for one aspect the first power management state may be a deeper sleep (C4) state, and the processor may quickly exit to a C2 state in response to a bus event such as a bus snoop.

摘要： Embodiments of the present invention provide a method and apparatus for detecting an interruption in memory initialization. A status bit for indicating whether memory initialization was interrupted or not is stored in a register. A basic input/output system (BIOS) sets the status bit prior to initialization and clears the status bit after initialization. The status bit cannot be reset by a standard platform reset. In operation, as the system is reset or turned on and prior to initialization, the BIOS checks the status bit to detect possible improper memory initialization. When the status bit is set, the BIOS concludes that a memory initialization had not completed and thus might be incorrect. The BIOS then causes power to be cycled to memory and any other steps needed are taken to return the memory to a functional state.

摘要翻译： 本发明的实施例提供了一种用于检测存储器初始化中的中断的方法和装置。 用于指示存储器初始化是否中断的状态位是否存储在寄存器中。 基本输入/输出系统（BIOS）在初始化之前设置状态位，并在初始化后清除状态位。 状态位不能通过标准平台复位来复位。 在操作中，当系统复位或打开和初始化之前，BIOS检查状态位以检测可能的不正确的存储器初始化。 当状态位置位时，BIOS得出结论：存储器初始化尚未完成，因此可能不正确。 BIOS然后使电源循环到存储器，并且采取任何其他步骤来将存储器返回到功能状态。
