    Abstract: Error correction circuitry (101) attempts to detect and correct, on-the-fly, erroneous words from RAM (102) within a computer system. Correctable errors are scrubbed without delaying the memory access cycle. The address of the section or row of RAM containing the correctable error is latched (130) for later use by a firmware-implemented interrupt-driven scrub routine (104) that reads and rewrites each word within the indicated memory section, resulting in the erroneous word being corrected on-the-fly and rewritten correctly. If the memory section size exceeds a threshold, the scrub process is divided into smaller subprocesses that are distributed in time using a delayed interrupt mechanism. Subprocess duration is kept short enough to avoid impairing the computer system response time. System management interrupts (120) and firmware (104) make the scrub routine independent of and transparent to the operating systems that may be run on the computer system.

    Abstract: Methods, apparatuses and storage medium associated with securely provisioning a digital content protection scheme are disclosed. In various embodiments, a method may include forming a trust relationship between a media application within an application execution environment of a device and a security controller of the device. The application execution environment may include an operating system, and the operating system may control resources within the application execution environment. Additionally, the security controller may be outside the application execution environment, enabling components of the security controller to be secured from components of the operating system. Further, the method may include the security controller in enabling a digital content protection scheme for the media application to provide digital content to a digital content protection enabled transmitter within the application execution environment for provision to a digital content protection enabled receiver. Other embodiments may be disclosed or claimed.
