US Patent:

20060221267, Oct 5, 2006

Filed:

Mar 29, 2005

Appl. No.:

11/092648

Inventors:

Cynthia Bell - Chandler AZ, US
Thomas Willis - Mountain View CA, US
Paul Winer - Santa Clara CA, US
Anders Grunnet-Jepsen - San Jose CA, US

International Classification:

G02F 1/1335

US Classification:

349005000

Abstract:

A projection display system may use a microdisplay that has pixels that are dedicated to only one narrow wavelength band. A suitable optical filter for each primary display color may be formed from a small number of optical layers, taking advantage of both the rounded profile and narrow range of the emission peaks in a typical projection light source. Thus, groups of pixels may be dedicated to each wavelength band of the display. A planarization layer may be coated on dichroic filter elements that are applied to a cover glass to provide the dedicated wavelengths for each pixel. The planarization layer may smooth out any surface irregularities resulting from the deposition of the dichroic layers on the cover glass.

International Classification:

H04L 12/851

Abstract:

A network switch includes a memory device to store a stream information of a plurality of data streams being handled by the network switch, the stream information including a stream identifier, a stream service level agreement (SLA), and a stream traffic type; accelerator circuitry to apply stream transformation functions to data streams; telemetry circuitry to monitor egress ports of the network switch; and scheduler circuitry to: receive telemetry data from the telemetry circuitry to determine that a utilization of egress ports of the network switch is over a threshold utilization; determine a selected data stream of the plurality of data streams to transform; use the accelerator circuitry to transform the selected data stream to produce a transformed data stream, wherein the transformed data stream complies with a corresponding stream SLA; and transmit the transformed data stream on an egress port.

Abstract:

Methods and Apparatus for Multi-Stage VM Virtual Network Function and Virtual Service Function Chain Acceleration for NFV and needs-based hardware acceleration. Compute platform hosting virtualized environments including virtual machines (VMs) running service applications performing network function virtualization (NFV) employ Field Programmable Gate Array (FPGA) to provide a hardware-based fast path for performing VM-to-VM and NFV-to-NFV transfers. The FPGAs, along with associated configuration data are also configured to support dynamic assignment and performance of hardware-acceleration to offload processing tasks from processors in virtualized environments, such as cloud data centers and the like.
