  • Publication number: 20180173545
    Abstract: Various embodiments include nested emulation for a source application and source emulator. Duplicate source ISA libraries redirect the source emulator library calls to a target library, thereby forcing the native emulator through proper emulation channels between first and second ISAs. Other embodiments concern accelerating dynamic linking by determining certain function calls that, rather than being processed through emulation of PLT code, are instead directly called without the need for PLT code translation. Some embodiments address both nested emulation and accelerated dynamic linking but other embodiments include one of nested emulation and accelerated dynamic linking. Other embodiments are described herein.

  • Patent number: 9989586
    Abstract: A converter circuit is provided. The converter circuit includes a capacitor module, bridge arms, a voltage measuring module and an open-circuit detection module. Each bridge arm is connected to the capacitor module in parallel and includes an upper arm and a lower bridge arm connected at a middle point. The voltage measuring module measures voltage differences between each two bridge arms. The open-circuit detection module transmits test impulse signals to the bridge arms to activate at least one upper-conducted bridge arm and at least one lower-conducted bridge arm. The open-circuit detection module retrieves the voltage differences of each pair of the upper-conducted and lower-conducted bridge arms to make comparison with a reference value to determine an operation state thereof, and makes comparison of the operation state determined according to the different groups of test impulse signals to determine whether the upper and the lower bridge arms are actually open circuit.

  • Patent number: 9967038
    Abstract: Techniques are described for data transfer in spin-based systems where digital bit values are represented by magnetization states of magnetoresistive devices rather than voltages or currents. For data transmission, a spin-based signal is converted to an optical signal and transmitted via an optical transport. For data reception, the optical signal is received via the optical transport and converted back to a spin-based signal. Such data transfer may not require an intervening conversion of the spin-based signal to charge-based signal that relies on voltages or currents to represent digital bit values. In addition, techniques are described to use magnetoresistive devices to control the amount of current or voltage that is delivered, where the magnetization state of the magnetoresistive device is set by an optical signal.
