  • Patent number: 7805597
    Abstract: A link based system including a plurality of processors is reset when transitioning from a slower speed to a higher speed mode during a booting process. One processor may coordinate the simultaneous establishment of link resetting of a plurality of other processors. In one embodiment, the processors may operate beginning with the farthest processor to reset their local links. Each processor sets its local links and if it determines, based on the speed of the link that the link has already been reset, it moves on to the next link.

  • Publication number: 20100110934
    Abstract: A spanning tree is assigned to a processing node for each processing node in a point-to-point network that connects a plurality of processing nodes. The spanning tree uses the processing nodes as vertices and links of the network as edges. Each processing node includes input snoop ports that can be configured as either terminating or forwarding. According to the assigned spanning trees and the configuration of the input snoop ports, the network routes snoop messages efficiently and without conflicts.

  • Patent number: 7572298
    Abstract: An implantable medical device is disclosed. The device is fabricated at least in part from a biocompatible, biodegradable composition. The composition is composed of a biocompatible, biodegradable polymer and a biocompatible, biodegradable wax. The concentration of the wax at the surface of the device is greater than the concentration of the wax in the body of the implantable device. The increased concentration of wax at the device surface may be attained when the device is heated to a temperature greater than the melting point of the wax and the glass transition temperature of the polymer, but lower than melting point of the polymer.

  • Patent number: 7555638
    Abstract: When a processing system boots, an image loader may determine whether a portable executable (PE) image for a platform firmware runtime service includes a discardable section. The image loader may load part of the PE image into runtime memory to be used by the platform firmware. In response to determining that the PE image includes a discardable section, the image loader may omit at least part of the discardable section when loading the PE image into the runtime memory. Instead, the image loader may load the discardable section into boot-time memory. In another embodiment, the image loader may pre-allocate an area of runtime memory for PE images, and may load sections from multiple PE images into the pre-allocated area. Also, the image loader may use an alignment granularity that is smaller than the page size when loading the PE images into the pre-allocated area. Other embodiments are described and claimed.
