Abstract: Systems and methods are disclosed for reusing fetched and decoded instructions in block-based processor architectures. In one example of the disclosed technology, a system includes a plurality of block-based processor cores and an instruction scheduler. A respective core is capable of executing one or more instruction blocks of a program. The instruction scheduler can be configured to identify a given instruction block of the program that is resident on a first processor core of the processor cores and is to be executed again. The instruction scheduler can be configured to adjust a mapping of instruction blocks in flight so that the given instruction block is re-executed on the first processor core without re-fetching the given instruction block.

Abstract: Dynamically replicated memory is usable to allocate new memory space from failed memory pages by pairing compatible failed memory pages to reuse otherwise unusable failed memory pages. Dynamically replicating memory involves detecting and recording memory faults, reclaiming failed memory pages for later use, recovering from detected memory faults, and scheduling access to replicated memory pages.

Abstract: A “Shared Tactile Immersive Virtual Environment Generator” (STIVE Generator) constructs fully immersive shared virtual reality (VR) environments wherein multiple users share tactile interactions via virtual elements that are mapped and rendered to real objects that can be touched and manipulated by multiple users. Generation of real-time environmental models of shared real-world spaces enables mapping of virtual interactive elements to real objects combined with multi-viewpoint presentation of the immersive VR environment to multiple users. Real-time environmental models classify geometry, positions, and motions of real-world surfaces and objects. Further, a unified real-time tracking model comprising position, orientation, skeleton models and hand models is generated for each user. The STIVE Generator then renders frames of the shared immersive virtual reality corresponding to a real-time field of view of each particular user.

Abstract: To protect customer data and provide increased workflow security for processing requested by a customer, a secure communicational channel can be established between a customer and one or more hardware accelerators such that even processes executing on a host computing device hosting such hardware accelerators are excluded from the secure communicational channel. An encrypted bitstream is provided to hardware accelerators and the hardware accelerators obtain therefrom cryptographic information supporting the secure communicational channel with the customer. Such cryptographic information is stored and used exclusively from within the hardware accelerator, rendering it inaccessible to processes executing on a host computing device. The cryptographic information can be a shared secret, an appropriate one of a pair of cryptographic keys, or other like cryptographic information.

Abstract: Dynamic power routing is utilized to route power from other components, which are transitioned to lower power consuming states, in order to accommodate more efficient processing of computational tasks by hardware accelerators, thereby staying within electrical power thresholds that would otherwise not have accommodated simultaneous full-power operation of the other components and such hardware accelerators. Once a portion of a workflow is being processed by hardware accelerators, the workflow, or the hardware accelerators, can be self-throttling to stay within power thresholds, or they can be throttled by independent coordinators, including device-centric and system-wide coordinators.

Abstract: In general, the short range wireless powered ring described herein pertains to a finger-worn ring. In one embodiment the ring has a small interaction area towards the palm of the hand that employs sensors to sense user input and can interpret this input and other data. For example, the ring can interpret user input as scroll and select input actions. The ring communicates user interactions and other data wirelessly using a low-power wireless solution. The ring contains a coil and other circuitry for energy harvesting from short range wireless enabled devices such as, for example, NFC enabled phones, while users interact with their devices. A built in rechargeable battery is used to store the scavenged energy. The ring may also contain physiological and inertial sensors. The ring can provide a readily available input device of small form factor that has an easily accessible energy source for ease of use.

Abstract: An “AR Privacy API” provides an API that allows applications and web browsers to use various content rendering abstractions to protect user privacy in a wide range of web-based immersive augmented reality (AR) scenarios. The AR Privacy API extends the traditional concept of “web pages” to immersive “web rooms” wherein any desired combination of existing or new 2D and 3D content is rendered within a user's room or other space. Advantageously, the AR Privacy API and associated rendering abstractions are useable by a wide variety of applications and web content for enhancing the user's room or other space with web-based immersive AR content. Further, the AR Privacy API is implemented using any existing or new web page coding platform, including, but not limited to HTML, XML, CSS, JavaScript, etc., thereby enabling existing web content and coding techniques to be smoothly integrated into a wide range of web room AR scenarios.

Abstract: The transmission of multiple copies of data to other computing devices is optimized by minimizing the number of copies of such data transmitted through an expensive portion of the network. A store-and-forward methodology is utilized to transmit only a single copy through the expensive portion and the data is subsequently forked into multiple copies directed to multiple destination computing devices. Computing devices that are not intended destinations can be conscripted as intermediate computing devices, if appropriate to minimize copies of the data transmitted through an expensive portion. Additionally, accommodation can be made for data that is intolerant of out-of-order delivery by utilizing adaptive protocols that avoid mechanisms that may result in out-of-order delivery for data intolerant of such and by utilizing packet sorting at data convergence points to reorder the data. Different protocol settings can be utilized to transmit data across different portions of the network.

Abstract: Various technologies described herein pertain to prefetching content units. A prefetch request is transmitted to a server from a client device. The prefetch request includes data indicative of probabilities of slots for content units being available during an upcoming time period. The probabilities can be based on likely interaction with application(s) executed by the client device during the upcoming time period. Prefetched content units assigned to the client device for the upcoming time period can be received from the server responsive to the prefetch request. One or more of the prefetched content units can be served for display on a display screen of the client device during execution the application(s). Further, statuses of the prefetched content units can be monitored, and information that specifies a subset of the prefetched content units that are unlikely to be displayed on the display screen prior to corresponding deadlines for expiration can be transmitted.

Abstract: Various technologies described herein pertain to allocating content units to client devices. Content units can be requested from an exchange by a server. The content units can be received by the server from the exchange, where the content units each has a corresponding deadline for expiration. Further, an indication of a penalty can be transmitted to the exchange if one of the content units is not displayed by one or more client devices upon expiration of the corresponding deadline.

Abstract: Specialized processing devices comprise both processing circuitry that is pre-configured to perform a discrete set of computing operations more quickly than generalized central processing units and network transport circuitry that communicationally couples each individual specialized processing device to a network as its own unique network client. Requests for hardware acceleration from workflows being executed by generalized central processing units of server computing devices are directed to hardware accelerators in accordance with a table associating available hardware accelerators with the computing operations they are optimized to perform. Load balancing, as well as dynamic modifications in available hardware accelerators, is accomplished through updates to such a table.

Abstract: Various technologies described herein pertain to prefetching advertisements for mobile advertising. A prediction model for estimating a number of advertisements that a mobile client is likely to request during an upcoming prediction time period can be employed. An estimated total amount of time of likely interaction with application(s) executed by the mobile client can be predicted; based upon such prediction, a number of advertisement slots likely to be available and a probability of each of the advertisement slots being available can be computed. Moreover, an ad server can allocate advertisements in a pending advertisement queue and/or disparate advertisements collected from an ad exchange to the mobile client based upon the number of advertisement slots likely to be available, the probability of each of the advertisements slots being available, and aggregated probabilities of the pending advertisements in the pending advertisement queue being displayed prior to corresponding deadlines for expiration.
