    摘要: Methods and systems are provided for encrypting data from a plurality of multimedia devices. A driver initiates authentication for the plurality of multimedia applications. The driver assigns a key registers to each of the applications, based on available key registers. The applications use generated encryption key values to send data to be decrypted by their assigned key registers. The driver notifies video processing hardware of encryption seed keys to determine the generated encryption key values and hardware stores the value of corresponding decryption keys the assigned key registers. Each register can be used to exclusively decrypt data from an application of the plurality of applications. The driver directs the encrypted data from the applications to the video processing hardware. The video processing hardware decrypts the data and processes it into image data accordingly.

    摘要: A system and methods are shown for improved processing of motion compensated video. A software driver handles image data related to motion compensated video. The image data includes IDCT coefficients and motion compensation vector data. A unique identifier is attached to the image data, preserving the relationship between the IDCT coefficients and motion compensated vector data related to an image block. The software driver sends the IDCT coefficients to an IDCT component. The IDCT coefficients are processed and an interrupt is sent to the software driver including the unique identifier of the processed IDCT coefficients. The software driver sends the motion compensation vector data related to the unique identifier in the interrupt. A 3D pipe receives the motion compensation vector data and reads the corresponding processed IDCT data. The 3D pipe sends an interrupt allowing the software driver to submit new IDCT coefficients as the 3D pipe processes the current motion compensation data with the read IDCT data. The 3D pipe processes the motion compensation data along with the read IDCT data to generate at least a portion of an image. The image portion is stored in a frame buffer until it is ready to be displayed.

    摘要: To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.

    摘要: Described herein are methods, systems and apparatus to improve imaging sensor production yields. In one method, a stereoscopic image sensor pair is provided from a manufacturing line. One or more images of a correction pattern are captured by the image sensor pair. Correction angles of the sensor pair are determined based on the images of the correction pattern. The correction angles of the sensor pair are represented graphically in a three dimensional space. Analysis of the graphical representation of the correction angles through statistical processing results in a set of production correction parameters that may be input into a manufacturing line to improve sensor pair yields.

    摘要: A graphics multi-media integrated circuit (GMIC) is connected to a host processor over two serial links: a half duplex bi-directional serial link which accords to a display serial interface protocol, and a uni-directional serial link which accords to a camera serial interface protocol. The GMIC receives packets from the host over the half duplex bi-directional serial link and processes these packets. The GMIC sends packets over the uni-directional serial link. A packet from the host can request a processing operation by the GMIC or can initiate a memory operation at the memory of the GMIC. The GMIC can also send packets to the host to initiate a host memory operation and may be connected to a display over a bi-directional serial link and to a camera over a uni-directional serial link and a bi-directional control link allowing the host to control the display and camera.

The controller provides power for a higher priority feature at the expense of a lower priority functional processing capability feature consistent with the user prioritized functional processing capability features. A wireless portable device is also disclosed that includes a wireless signal strength determinator that determines a received signal strength of the wireless device and a controller that adjusts the functional processing capability feature of the wireless device based on the determined received signal strength and based on battery capacity information. In this way, received signal strength information is used as a further input to determine how to best adjust functional processing capability features of the device.

    摘要: An error detection apparatus and method compares a first hardwired value such as a first clock threshold, and a second hardwired value such as a second clock threshold, and generates an indication that there is an error in a clock signal based on a comparison of the first hardwired value and the second hardwired value to the clock signal. If an error is detected, the error detection apparatus will, for example, interrupt clock recovery logic to take proper action for recovery of a clock generation circuit that generated the clock signal. The clock signal may be generated based on, for example, a reference clock signal that may be provided by an external source clock, or any other suitable source.

    摘要: A method includes determining white balance calibration color ratios for a plurality of illumination sources by using a representative camera of a given type to establish a set of ratios. Because the ratios are fixed for the given camera type, a plurality of cameras of the type may store the fixed ratios, and calibrate by measuring only the reference illumination source. Later white balancing is achieved by using the measured reference illumination source color ratios and the stored fixed ratios as scaling factors to map from the reference illumination source to any other illumination source. The method includes an off-line advance calibration procedure to obtain the fixed ratios, an on-line per camera calibration procedure to obtain color ratios for the reference source, and subsequent white balancing which uses the fixed ratios/scaling factors and the reference source color ratios.

    摘要: In a device, such as a cell phone, memory resource sharing is enabled between components, such as integrated circuits, each of which has memory resources. This may be accomplished by providing an interconnect between the components and constructing transaction units which are sent over the interconnect to initiate memory access operations. The approach may also be used to allow for a degree of communication between device components.
