  • Patent number: 9189426
    Abstract: Embodiments of techniques and systems for protected access to virtual memory are described. In embodiments, a protected memory management architecture (“PMMA”) may be configured to control accesses to protected physical memory. The PMMA may provide a protected virtual memory window for dynamic allocation of protected memory regions. During forward translation of virtual memory addresses, the PMMA may check a region ID of a process before allowing access. During reverse translation of a physical memory address, the PMMA may prevent accesses to protected physical memory addresses. The PMMA may also dynamically allocate physical memory to protected memory regions in virtual memory and may authenticate the physical memory as available before allocation. Other embodiments may be described and claimed.

  • Publication number: 20120272272
    Abstract: Methods and systems to present data to a viewer, where the data is specific to the viewer and his viewing experience and is stored locally. This data may be, for example, supplemental content or an application, such as a widget. In an embodiment, supplemental content, such as advertising, may be presented to the viewer where this content is aimed at the particular viewer in light of his or her viewer profile. In an alternative embodiment, a widget or other application may be presented to the viewer where the widget is specific to the current programming and thus tailored to the viewer's current viewing experience. In both situations, the data is stored locally and made available with minimal delay.
