  • Patent number: 11823757
    Abstract: Volatile memory devices may be on a first memory module that is coupled to a memory controller by a first signal path. A nonvolatile memory device may be on a second memory module that is coupled to the first memory module by a second signal path. A memory transaction for the nonvolatile memory device may be transferred from the memory controller to at least one of the volatile memory devices using the first signal path and data associated with the memory transaction is to be written from at least one of the volatile memory devices to the nonvolatile memory device using the second signal path and a control signal. A durability circuit may generate the control signal based on a comparison of a number of write transactions to a particular memory location with a threshold value.

  • Patent number: 8966413
    Abstract: A chip generator according to an embodiment of the present invention codifies designer knowledge and design trade-offs into a template that can be used to create many different chips. Like reconfigurable designs, an embodiment of the present invention fixes the top level system architecture, amortizes software and validation and design costs, and enables a rich system simulation environment for application developers. Meanwhile, below the top level, the developer can “program” the individual inner components of the architecture. Unlike reconfigurable chips, a chip generator according to an embodiment of the present invention, compiles the program to create a customized chip. This compilation process occurs at elaboration time—long before silicon is fabricated. The result is a framework that enables more customization of the generated chip at the architectural level because additional components and logic can be added if the customization process requires it.

  • Patent number: 8892619
    Abstract: A floating-point fused multiply-add (FMA) unit embodied in an integrated circuit includes a multiplier circuit cascaded with an adder circuit to produce a result A*C+B. To decrease latency, the FMA includes accumulation bypass circuits forwarding an unrounded result of the adder to inputs of the close path and the far path circuits of the adder, and forwarding an exponent result in carry save format to an input of the exponent difference circuit. Also included in the FMA is a multiply-add bypass circuit forwarding the unrounded result to the inputs of the multiplier circuit. The adder circuit includes an exponent difference circuit implemented in parallel with the multiplier circuit; a close path circuit implemented after the exponent difference circuit; and a far path circuit implemented after the exponent difference circuit.

    Abstract: A system for recycling energy from ice remnants. The system includes a container. The container includes a receptacle configured to receive ice remnants. An ice capturing and melting device below the receptacle is configured to capture and melt ice in the ice remnants while allowing fluid in the ice remnants to pass therethrough thereby forming a cooled recycled liquid at a bottom of the container. A discharge port located proximate the bottom of the container is configured to direct the cooled recycled liquid to at least one heat source of a facility and cool the heat source.

  • Patent number: 8185853
    Abstract: Embodiments in the present disclosure pertain to domain translators. A domain translator converts a variable from one domain to a different domain. Domains include, but are not limited to, voltage, current, frequency, phase, delay, and duty-cycle. In particular, domain translators enable conversion between standard voltage and current domains commonly used by circuit simulators to other domains such as frequency, phase, delay, duty-cycle, etc., so that linear analysis can be performed on a wide range of circuits that exhibit linear behavior in domains other than voltage and current.

  • Patent number: 8027531
    Abstract: This invention relates to an apparatus and a method for video capture of a three-dimensional region of interest in a scene using an array of video cameras. The video cameras of the array are positioned for viewing the three-dimensional region of interest in the scene from their respective viewpoints. A triggering mechanism is provided for staggering the capture of a set of frames by the video cameras of the array. The apparatus has a processing unit for combining and operating on the set of frames captured by the array of cameras to generate a new visual output, such as high-speed video or spatio-temporal structure and motion models, that has a synthetic viewpoint of the three-dimensional region of interest. The processing involves spatio-temporal interpolation for determining the synthetic viewpoint space-time trajectory. In some embodiments, the apparatus computes a multibaseline spatio-temporal optical flow.

  • Patent number: 7765074
    Abstract: A circuit, apparatus and method obtains system margin at the receive circuit using phase shifted data sampling clocks while allowing the CDR to remain synchronized with the incoming data stream in embodiments. In an embodiment, a circuit includes first and second samplers to sample a data signal and output data and edge information in response to a data clock signal and an edge clock signal. A phase detector generates phase information in response to the data information and the edge information. A clock phase adjustment circuit generates the data clock signal and the edge clock signal in response to the data information during a synchronization mode. The clock phase adjustment circuit increments a phase of the data clock signal during a waveform capture mode.
