Abstract: A method for a near field communication circuit includes entering a low power mode and subsequently determining to exit the low power mode. The method further includes generating an open loop clock signal and providing the open loop clock signal to circuits of the near field communication circuit during a low power mode exit duration. Subsequently a reference clock signal is received from a host and used to clock the near field communication circuit.

Abstract: The present disclosure is directed to a method and apparatus for providing an output oscillating signal at a desired frequency. In at least one example, the apparatus includes a weak inversion structure configured to set a small reference current. A current mirror configured to provide a replica current based on the small reference current and a tuning word. A ring oscillator is configured to be powered by a supply at a voltage determined based on the replica current. The tuning word is adjustable to change the voltage such that the ring oscillator provides the output oscillating signal at the desired frequency.

Abstract: This disclosure describes an apparatus, such as a wireless communication device, that applies a direct evaluation technique to render triangles for the 3D graphical environment. The apparatus includes a rendering engine that defines a rectangular area of pixels, referred to as a bounding box, that bounds the area to be rendered. The rendering engine evaluates coordinates associated with the pixels of the rectangular area to selectively render those pixels that fall within the triangular area. The direct evaluation triangle rendering algorithm may require fewer complex operations than the more computationally intensive interpolation process employed by other systems. As a result, the apparatus may present a 3D graphical environment while preserving as much as possible the available power.

Abstract: In general, the invention is directed toward a device for processing digital video data, such as an encoder, a decoder or an encoder/decoder (CODEC). The device makes use of an innovative architecture in which functionality is partitioned between an embedded processor, a digital signal processor and dedicated hardware to achieve increased performance. In addition, the device includes a programmable video direct memory access (VDMA) controller to retrieve video data from memory in response to a command specifying a multidimensional block of video data.

Abstract: A graphics pipeline includes a plurality of sequentially arranged processing stages which render display pixel data from input primitive object data. The processing stages include at least a texturing stage and a depth test stage, and the depth test stage may be located earlier in the graphics pipeline than the texturing stage.
