  • Publication number: 20120170472
    Abstract: Embodiments of the invention include a method for avoiding memory bandwidth utilization during packet processing. The packet processing core receives a plurality of packets. The packet processing core identifies the packet's quality of service (QoS) descriptor. The packet processing core determines that at least one packet should be moved to an off-chip packet stored prior to the packet being transmitted to the egress port. The packet processing core bases that determination, at least in part, on the packet's QoS descriptor. The packet processing core moves the determined packets to the off-chip packet store. The packet processing core determines that at least one packet should not be moved to the off-chip packet store prior to the packet being transmitted to the egress port. This determination is also made, at least in part, based on the packet's QoS descriptor.

  • Patent number: 7986706
    Abstract: A hierarchical pipelined distributed scheduling traffic manager includes multiple hierarchical levels to perform hierarchical winner selection and propagation in a pipeline including selecting and propagating winner queues of a lower level to subsequent levels to determine one final winning queue. The winner selection and propagation is performed in parallel between the levels to reduce the time required in selecting the final winning queue. In some embodiments, the hierarchical traffic manager is separated into multiple separate sliced hierarchical traffic managers to distributively process the traffic.

  • Publication number: 20110062471
    Abstract: An array of housings with housing bodies and lenses is molded, or an array of housing bodies is molded and bonded with lenses to form an array of housings with housing bodies and lenses. Light-emitting diodes (LEDs) are attached to the housings in the array. An array of metal pads may be bonded to the back of the array or insert molded with the housing array to form bond pads on the back of the housings. The array is singulated to form individual LED modules.

  • Publication number: 20110062469
    Abstract: A light emitter includes a light-emitting device (LED) die and an optical element over the LED die. The optical element includes a lens, a window element, and a bond at an interface disposed between the lens and the window element. The window element may be a wavelength converting element or an optically flat plate. The window element may be directly bonded or fused to the lens, or the window element may be bonded by one or more intermediate bonding layers to the lens. The bond between the window element and the lens may have a refractive index similar to that of the window element, the lens, or both.

  • Publication number: 20030175030
    Abstract: A reconfigurable liquid crystal based optical add/drop multiplexer system and method are provided which incorporates switching, variable attenuation, and multiplexing/demultiplexing capabilities. In a preferred embodiment, an array of optical rails is provided such that the integration of multiplexing/demultiplexing, switching, and variable optical attenuation functionalities are achieved. The module is also able to perform add and drop functions independently. The system has no moving parts so that the module is durable and very reliable. The system may include a feedback system for performing channel equalization.

  • Patent number: 6204304
    Abstract: The specification describes optical fiber coating materials and methods for making optical fiber gratings wherein the material of the optical fiber coatings comprises vinyl ether functionalized monomers, together with oligomeric or polymeric thickeners and a cationic photoinitiator. These coating materials are highly transparent to UV radiation used to write optical gratings in the optical fibers but still absorb sufficiently at other wavelengths to be cured effectively using UV radiation.

  • Patent number: 5852313
    Abstract: A flash memory cell structure comprising a semiconductor substrate having a first transistor and a second transistor formed thereon. The first transistor has a stacked gate and a first source/drain regions, wherein the stacked gate further includes a floating gate and a control gate. The control gate is formed above the floating gate. The second transistor is electrically connected in series with the first transistor. The second transistor functions as a select transistor and includes a gate and a second source/drain regions.

  • Patent number: 5490257
    Abstract: A method for detecting a half-full condition of a first-in, first-out memory array. The method of the invention includes the steps of a) moving a write pointer through the array to write data to alternating rows of the memory array; b) moving a read pointer through the array to read data from the alternating rows of the memory array in first-in, first-out order; and c) providing a half-full indication when the read pointer and the write pointer point to adjacent rows in the memory array. This method eliminates the need to route lines across the array to detect a half-full condition, thereby reducing die and power requirements and offering an increase in speed.
