  • Patent number: 8032762
    Abstract: A wireless communications device (110) has a digital section (800) and a radio frequency section (840). The digital section (800) does setup and execution on a set of data in at least first and second threads concurrently in a series of overlapping iterations by dividing the set of data into at least two different subsets and concurrently reading and writing in both subsets. A state machine (1010, 1100) is shared by the setup and execution iterations. Two or more memory units (930, 940) segregate the set of data, the predetermined size of the set of data in the memories (930, 940) combined comprehending the total number of addresses occupied by the set of data utilized in operation of circuitry (910). Dirty bits (1430) are accessible at addresses corresponding to addresses in the memory. A selector circuit (1412) has a selector output selectively coupled to an address line, and to a data line.

  • Patent number: 7920020
    Abstract: A method includes parsing a design of the integrated circuit to define cells in automatic power gating power domains, automatically creating an automatic power gating power domain netlist from the parsed design of the integrated circuit, and placing and routing the automatic power gating power domain netlist to produce a layout for the integrated circuit. The parsing partitions a high-level power domain of the integrated circuit into one or more automatic power gating power domains. The automatic power gating power domains have substantially zero-cycle power up times, thereby enabling transparent operation. Furthermore, the automatic power gating power domains may be automatically inserted into designs of integrated circuits, thereby relieving integrated circuit designers of the task of inserting power domains and associated hardware and software.

  • Patent number: 7920081
    Abstract: An embodiment of the present invention provides a phase locked loop that operates on clock signals derived from an RF clock signal generated by the phase locked loop. A frequency reference input provides a reference clock. A controllable oscillator generates the RF clock signal. A phase detection circuit operates on the reference clock to provide digital phase error samples indicative of a phase difference between the reference clock and the RF clock. A dithering circuit is coupled to the reference signal and injects a short sequence dither signal into the reference signal in order to overcome quantization noise and thereby improve RMS phase-error detection for integer channels.

  • Patent number: 7899571
    Abstract: A method of conditioning a CMP polishing pad to attain a desired thickness profile in a polished layer on a wafer is disclosed. The incoming thickness profile of the layer to be polished, the thickness profile of the polishing pad, a polish rate of layer as a function of pressure and the removal rate of polishing pad material by a conditioning block are used to compute a sweep pattern for the conditioning block which will produce a desired thickness profile on the polishing pad. The method may be applied to maintaining the desired profile on the polishing pad during the course of polishing multiple wafers. The pad profile may be adjusted to keep pressure between the pad and the wafer to a safe limit to reduce polishing defects.
