Abstract: Methods and systems to sample a subset of primitives from a batch of primitives for cull/no-cull decisions, and to selectively perform a batch-cull operation on the batch of primitives in response to cull/no-cull decisions of the samples. Cull/no-cull decisions may be determined in response to one or more of a sign and magnitude of a z-component of a surface normal to corresponding primitives, using one or more primitive-independent, vertex-based cull codes, which may include a cull code based on 2-dimensional pixel space positions corresponding to the primitives. 2-dimensional pixel space positions may be pre-computed for vertices associated with a batch of primitives in advance of sampling culling.

Abstract: Embodiments of a network-enabled mass storage dongle with networked media content aggregation are discussed. Embodiments provide for a dongle in a consumption mode is inserted into one or more source devices, where the one or more source devices are part of a network and store content to be aggregated for accessing on equipment. In embodiments the equipment has no intrinsic networking capabilities. The dongle allows a user to select one or more directory structures on each of the one or more source devices to be included in the aggregated content. The dongle then creates a file share for each of the selected directory structures. The dongle in an aggregation mode is inserted into the equipment and automatically connects to the network. The dongle aggregates content in the created file shares to present the aggregated content as a single mass storage device to the equipment. Other embodiments are described and claimed.

Abstract: A method and system to lower the minimum operating voltage of a register file without increasing the area of each bit cell of the register file. In one embodiment of the invention, the register file is coupled to logic that reduces the contention between the NMOS devices and the PMOS devices in each bit cell of the register file during write and/or read operations of the register file. By doing so, the register file is able to operate at a lower minimum operating voltage.

Abstract: Domain-based cache management methods and systems, including domain event based priority demotion (“EPD”). In EPD, priorities of cached data blocks are demoted upon one or more domain events, such as upon encoding of one or more macroblocks of a video frame. New data blocks may be written over lowest priority cached data blocks. New data blocks may initially be assigned a highest priority. Alternatively, or additionally, one or more new data blocks may initially be assigned one of a plurality of higher priorities based on domain-based information, such as a relative position of a requested data block within a video frame, and/or a relative direction associated with a requested data block. Domain-based cache management may be implemented with one or more other cache management techniques, such as least recently used techniques. Domain-based cache management may be implemented in associative caches, including set associative caches and fully associative caches, and may be implemented with indirect indexing.

Abstract: Methods and systems to generate multiple phases of a clock may include a delay locked loop (DLL) to generate a bias signal to control a delay time through DLL delay elements in response to a first clock, and a plurality of a quadrature slave delay lines (SDLs), each to generate a plurality of successively phase shifted clocks over a quadrant of a corresponding selected phase of a second clock. The SDLs may be biased with the DLL bias signal to control phase differences between the generated clocks. One or more phase interpolators, such as contention based phase interpolators, may be coupled to outputs of each SDL. A frequency of the second clock may be equal to or greater than a frequency of the first clock. The SDLs may be implemented with fewer delay elements than the DLL.

Abstract: Embodiments of apparatus, articles, methods, and systems for secure platform voucher service for software components within an execution environment are generally described herein. An embodiment includes the ability for a Virtual Machine Monitor, Operating System Monitor, or other underlying platform capability to restrict memory regions for access only by specifically authenticated, authorized and verified software components, even when part of an otherwise compromised operating system environment.

The verification proof or voucher helps to assure to the remote entity that no man-in-the-middle, rootkit, spyware or other malware running in the platform or on the network will have access to the provisioned material.
