  • Patent number: 9996358
    Abstract: A system and method of coupling a Branch Target Buffer (BTB) content of a BTB with an instruction cache content of an instruction cache. The method includes: tagging a plurality of target buffer entries that belong to branches within a same instruction block with a corresponding instruction block address and a branch bitmap to indicate individual branches in the block; coupling an overflow buffer with the BTB to accommodate further target buffer entries of instruction blocks, distinct from the plurality of target buffer entries, which have more branches than the bundle is configured to accommodate in the corresponding instruction's bundle in the BTB; and predicting the instructions or the instruction blocks that are likely to be fetched by the core in the future and fetch those instructions from the lower levels of the memory hierarchy proactively by means of a prefetcher.

  • Patent number: 9978285
    Abstract: A navigation system including a vehicle dynamic model (VDM) that serves as the main process model within a navigation filter is described. When used in an unmanned aerial vehicle (UAV), the navigation system may work in communication with inertial measurement units (IMUs) and environment dependent sensors such as GNSS receivers. Particularly, the navigation system is beneficial in the case of GNSS signal reception outages, where conventional IMU coasting drifts quickly. Yet, the navigation system may also be employed in other scenarios, for example during GNSS presence for improved positioning, velocity and attitude determination, or in combination with GNSS when no IMU is available by design or due to a failure. In the navigation system, a solution to VDM equations provides an estimate of position, velocity, and attitude, which can be updated within a navigation filter based on available observations, such as IMU data or GNSS measurements.

  • Patent number: 9909218
    Abstract: A method and apparatus for local beam processing using a beam activated gas to etch material are described. Compounds are disclosed that are suitable for beam-induced etching. The invention is particularly suitable for electron beam induced etching of chromium materials on lithography masks. In one embodiment, a polar compound, such as ClNO2 gas, is activated by the electron beam to selectively etch a chromium material on a quartz substrate. By using an electron beam in place of an ion beam, many problems associated with ion beam mask repair, such as staining and riverbedding, are eliminated. Endpoint detection is not critical because the electron beam and gas will not etch significantly the substrate.

  • Publication number: 20180031376
    Abstract: System and methods for computing true wind and true current are described. True wind estimation occurs through automatic calibration of data obtained from data acquisition devices (102, 114, 116, 118, 120). Real-time boat performance information is generated through automatic target speed computation. Maneuvers are found in data obtained from the data acquisition devices (102, 114, 116, 118, 120) and, if properly calibrated, wind just prior to a maneuver should be the same as measured wind just after the maneuver. If the measured wind values are not equal, the sum of the wind difference over all maneuvers is minimized.
