  • Patent number: 8463975
    Abstract: In one embodiment, the present invention includes an apparatus having an adapter to communicate according to a personal computer (PC) protocol and a second protocol. A first interface coupled to the adapter is to perform address translation and ordering of transactions received from upstream of the adapter. The first interface is coupled in turn to heterogeneous resources, each of which includes an intellectual property (IP) core and a shim, where the shim is to implement a header of the PC protocol for the IP core to enable its incorporation into the apparatus without modification. Other embodiments are described and claimed.

  • Publication number: 20130061077
    Abstract: In one embodiment, the present invention includes a method for sending a first link handshake signal between a first subsystem and a power management unit (PMU) of a system on a chip (SoC) to request entry into a power saving state for the first subsystem, sending a second link handshake signal between the first subsystem and the PMU to acknowledge the request, and placing the first subsystem into the power saving state without further signaling between the PMU and the first subsystem. Other embodiments are described and claimed.

  • Publication number: 20110242129
    Abstract: Embodiments of an apparatus, system and method are described for an edge-preserving smooth filter for low power architecture. A weighted pixel sum may be determined based on a weight of a central pixel and a weight of one or more neighboring pixels. The weight sum for the central pixel may be set to a power of two. An output of the central pixel may be displayed based on the weight sum and the weighted pixel sum. Other embodiments are described and claimed.
