  • Patent number: 11631625
    Abstract: A mechanism is provided to remove heat from an integrated circuit (IC) device die by directing heat through a waveguide to a heat sink. The waveguide is mounted on top of a package containing the IC device die. The waveguide is thermally coupled to the IC device die. The waveguide transports the heat to a heat sink coupled to the waveguide and located adjacent to the package on top of a printed circuit board on which the package is mounted. Embodiments provide both thermal dissipation of the generated heat while at the same time maintaining good radio frequency performance of the waveguide.

  • Patent number: 11630668
    Abstract: A processor including a pointer storage that stores pointer descriptors each including addressing information, an arithmetic logic unit (ALU) configured to execute an instruction which includes operand indexes each identifying a corresponding pointer descriptor, multiple address generation units (AGUs), each configured to translate addressing information from a corresponding pointer descriptors into memory addresses for accessing corresponding operands stored in a memory, and a smart cache. The smart cache includes a cache storage, and uses the memory addresses from the AGUs to retrieve and store operands from the memory into the cache storage, and to provide the stored operands to the ALU when executing the instruction. The smart cache replaces a register file used by a conventional processor for retrieving and storing operand information. The pointer operands include post-update capability that reduces instruction fetches. Wasted memory cycles associated with cache speculation are avoided.

  • Patent number: 11632829
    Abstract: A defrosting system includes an RF signal source, an electrode proximate to a cavity within which a load to be defrosted is positioned, and a transmission path between the RF signal source and the electrode. The system also includes power detection circuitry coupled to the transmission path and configured repeatedly to take forward and reflected RF power measurements along the transmission path. A system controller repeatedly determines, based on the forward and reflected RF power measurements, a calculated rate of change, and repeatedly compares the calculated rate of change to a threshold rate of change. When the calculated rate of change compares favorably with the threshold rate of change, the RF signal source continues to provide the RF signal to the electrode until a determination is made that the defrosting operation is completed, at which time the RF signal source ceases to provide the RF signal to the electrode.

In a correlator, a group of three correlation values is determined from the matching group of samples, including a local maximum correlation value, P0, an immediately preceding correlation value, Pm, and an immediately succeeding correlation value Pp. In an estimation unit, a polynomial function f(?) of the difference, ?, between Pm and Pp is used to estimate a timing offset Tfrac, between the local maximum correlation value and a correlation peak. The time-of-arrival is estimated from a time of the local maximum correlation value P0, and Tfrac.
