Abstract: Embodiments described herein are related to providing an improved quality of experience (QoE) for users consuming video content. An improved QoE may be provided to a user by allocating an appropriate bandwidth at which content is provided to the user. The appropriate bandwidth may be determined by an application function of the communications network used to provide the content to the user. The application function analyzes messages received from the content provider to determine characteristics of the content, determines the appropriate bandwidth accordingly, and generates a policy control rule to be enforced by the communications network when transmitting the content. Alternatively, a mobile device used to engage in the content determines the appropriate bandwidth at which video is to be transmitted thereto. The determined bandwidth is provided to the application function, which generates a policy control rule to be enforced by the communications network based on the determined bandwidth.

Abstract: A system and method includes generating, with a configuration controller, a configuration bitstream including configuration bits to dynamically define the configuration of a reconfigurable integrated circuit by setting a state of a subset of configuration state memory units. The configuration controller accesses individual configuration state memory units of the subset according to a scan path through the configuration state memory units traversed according to a delay factor based, at least in part, on clock frequency of a clock signal produced by a configuration clock and configures the individual configuration state memory units with corresponding configuration bits of the configuration bitstream.

Abstract: A system and method for using the system includes a first and second waveguide and optical receiver elements coupled therebetween. The optical receiver elements include a microring configured to admit light from and transfer light to at least one of the first and second waveguides, a photodetector, coupled to the microring, configured to detect light admitted to the microring, and an enable circuit, coupled to the microring, configured to be switched between a light admitting state to enable light to be admitted to the microring and a light rejection state to prevent light from being admitted to the microring. Each optical receiver element has a relative priority and are configured to asynchronously arbitrate among themselves for a token to place one of the enable circuits in the light admitting state to enable one of the optical receiver elements to receive and transmit data.

Abstract: The invention relates to hardware decoders that efficiently expand a small number of input bits to a large number of output bits, while providing considerable flexibility in selecting the output instances. One main area of application of the invention is in pin-limited environments, such as field programmable gates array (FPGA) used with dynamic reconfiguration. The invention includes a mapping unit that is a circuit, possibly in combination with a reconfigurable memory device. The circuit has as input a z-bit source word having a value at each bit position and it outputs an n-bit output word, where n>z, where the value of each bit position of the n-bit output word is based upon the value of a pre-selected hardwired one of the bit positions in the x-bit word, where the said pre-selected hardwired bit positions is selected by a selector address.

Abstract: A free space all-optical crossbar switches light from a plurality of sources onto a plurality of receivers, in any arbitrary permutation or combination (including one-to-one and many-to-one permutations). The sources and receivers may, for example, be single mode optical fibers. The polarization of the light from each source is controlled by a series of polarization control devices associated with the source so as to obtain desired angular deflections through a series of polarization-dependent angular deflectors in a first deflection unit. A lens may then direct the light from each source towards its desired receiver. An optional second deflection unit containing polarization control devices associated with individual receivers redirects the light so that it is incident normally on the receivers, an advantage if the receivers are single mode optical fibers. Alternative embodiments are described to reduce the number of optical components and to provide uninterrupted high speed data flow.

Abstract: Optical slab waveguides are used as high-speed, high-capacity interconnects for parallel or other devices. Optical slab interconnects can connect to many more elements than can conventional electrical or fiber optic buses. A multiplexing scheme called “mode division multiplexing” greatly increases the number of independent channels that a single slab can support. Optical slab waveguides have a potential capacity of over one million independent channels, each channel operating at 1 GHz in a single physical medium, with each channel capable of receiving input from over 1000 ports and sustaining a load of over 1000.
