  • Command protocol for adjustment of write timing delay
    Patent number: 8489912
    Abstract: A method, system, and computer program product are provided for adjusting write timing in a memory device based on a command protocol. For instance, the method can include enabling a write clock data recovery (WCDR) mode of operation. The method can also include transmitting WCDR data from a processing unit to the memory device during the WCDR mode of operation and another mode of operation of the memory device. Based on a phase shift in the WCDR data, a phase difference between a signal on a data bus and a write clock signal can be adjusted. Further, the method can include transmitting the signal on the data bus based on the adjusted phase difference between the signal on the data bus and the write clock signal.

  • METHOD AND SYSTEM FOR FRAME BUFFER PROTECTION
    Publication number: 20130166922
    Abstract: When content, such as premium video or audio, is decoded, the content is stored in protected memory segments. Read access to the protected memory segments from a component not in a frame buffer protected (FBP) mode is blocked by a memory controller. The memory controller also blocks components in the FBP mode from writing to unprotected memory segments. The content may be processed by a processing engine operating in the FBP mode and may only be written back to protected memory segments. The memory segment may later be marked as unprotected if the memory segment is no longer needed. If the content is encrypted in protected memory, the encrypting key associated with the memory segment may be removed. If the content is stored in the clear, the protected memory segments are scrubbed before releasing the segments for use as unprotected memory segments.

  • METHOD AND APPARATUS FOR CONFIGURING AN INTEGRATED CIRCUIT
    Publication number: 20130162289
    Abstract: A method and apparatus configures an integrated circuit by determining a multi-bit configuration value on a single node. The multi-bit configuration value is determined by using at least a voltage level at the single node and also by detecting a time to reach a voltage threshold level at the single node, based on a voltage ramp generation circuit. The method and apparatus also includes configuring an operation mode of a circuit in the integrated circuit based on the determined multi-bit configuration value from the single node. Multi-bit configuration values may be obtained on multiple single nodes in an integrated circuit. In one example, a voltage level is employed in addition to a time to reach a voltage threshold level whereas in another example a current level on a single node is utilized in combination with detection of a time to reach a voltage threshold level.

  • HIGH SPEED SERIAL INPUT/OUTPUT BUS VOLTAGE MODE DRIVER WITH TUNABLE AMPLITUDE AND RESISTANCE
    Publication number: 20130162300
    Abstract: A device having a voltage mode driver with tunable amplitude and resistance that supports a predetermined output resistance and output amplitude is described herein. The voltage mode driver includes multiple configurable drivers. The voltage mode driver is controlled by a control module. Resistance tuning is controlled by the number of active configurable drivers and amplitude tuning is controlled by setting the high or low drive state of each active configurable driver. The slew rate of the device is controlled by delaying the setting of the high or low drive state of an active configurable driver by a predetermined interval.

  • VERTICAL SCAN PANEL WITH CONVERSION MODE CAPABILITY
    Publication number: 20130162682
    Abstract: A method and apparatus for providing an image on a vertical scan panel determines whether a mode of operation for a vertical scan panel is either a scan conversion pass-through mode or a horizontal scan conversion mode. If the determined mode is the horizontal scan conversion mode, the method and apparatus converts display data in the vertical scan panel from a horizontal scan format to a vertical scan format and displays the converted display data on the vertical scan panel. However, if the determined mode is the scan conversion pass-through mode, the method and apparatus includes displaying display data on the vertical scan panel in a vertical scan format without applying a scan conversion operation on the display data.

  • DOWNSTREAM VIDEO COMPOSITION
    Publication number: 20130162911
    Abstract: A video source, a display and a method of processing multilayered video are disclosed. The video source decodes a multilayered video bit stream to transmit synchronized streams of decompressed video images and corresponding overlay images to an interconnected display. The display receives separate streams of video and overlay images. Transmission and reception of corresponding video and overlay images is synchronized in time. A video image received in the display can be selectively processed separately from its corresponding overlay image. The video image as processed at the display is later composited with its corresponding overlay image to form an output image for display.

  • WRITE DATA MASK METHOD AND SYSTEM
    Publication number: 20130166875
    Abstract: In various embodiments, dedicated mask pins are eliminated by sending a data mask on address lines of the interface. A memory controller receives a request for a memory write operation from a memory client and determines the granularity of the write data from a write data mask sent by the client. Granularity, as used herein, indicates a quantity of write data to which each bit of the received write data mask applies. In an embodiment, the memory controller generates a particular write command and a particular write data mask based on the granularity of the write data. The write command generated is typically the most efficient of several write commands available, but embodiments are not so limited. The write command is transmitted on command lines of the interface, and the write data mask is transmitted on address lines of the interface.

  • Offset tiles in vector graphics
    Patent number: 8471862
    Abstract: An efficient rendering method for processing computer graphics in tiles. First a frame of data, typically at least one polygon, is received for rendering. While rendering a polygon the tile for the polygon is assigned so that it minimizes the number of the tiles needed for processing the polygon. It is possible to compute an offset value between the static tiles and the assigned tiles. If the offset value is computed, the rendering into an actual screen may be based on that.
