    • In some embodiment, an arrangement is provided to prevent a loss of data in a memory due to a power failure for a computing system. When the power failure occurs, any pending memory write operations may be completed and dirty cache lines may be flushed back to the memory. Subsequently, the computing system may be put into a loss-prevention state, under which power may be turned off for all components in the computing system except the memory. The memory is powered by a battery pack which includes batteries and is in a self refresh state. When the power returns, applications and operating systems running in the computing system may resume what is left out when the power supply failure occurs, based at least in part on data retained in the memory. Other embodiments are described and claimed.
    • 在一些实施例中,提供一种布置以防止由于计算系统的电力故障而导致存储器中的数据丢失。 发生电源故障时,可能会完成任何挂起的内存写入操作,并且脏高速缓存行可能会被刷新回内存。 随后,计算系统可以进入防止丢失状态,在该状态下,除了存储器之外,可以关闭计算系统中的所有组件的电力。 内存由包含电池的电池组供电,并处于自刷新状态。 当电源恢复时,在计算系统中运行的应用程序和操作系统可以恢复当电源发生故障时遗漏的内容,至少部分基于保存在存储器中的数据。 描述并要求保护其他实施例。

    • According to one embodiment, computer system is disclosed. The computer system includes a central processing unit (CPU), and a chipset coupled to the CPU including protected registers and a host controller. The computer system also includes a bus coupled to the host controller and a peripheral device coupled the bus. Trusted software accesses the protected registers to transmit encrypted data between the host controller and the peripheral device upon startup of the computer system to verify that the peripheral device is trustworthy.
    • 根据一个实施例,公开了一种计算机系统。 计算机系统包括中央处理单元(CPU)和耦合到CPU的芯片组,包括受保护的寄存器和主机控制器。 计算机系统还包括耦合到主控制器的总线和耦合总线的外围设备。 受信任的软件访问受保护的寄存器,以在计算机系统启动时在主机控制器和外围设备之间传输加密数据,以验证外围设备是否可靠。
