    摘要： Provided is a method and system for performing color look-up table (CLUT) and gamma correction for video pixel data. A system includes a memory configured for storing CLUT parameters and gamma correction parameters therein. Also included is an input matrix coupled to the memory and configured to receive first and second type pixel data. The memory receives the first type pixel as an address to the stored CLUT parameters and receives the second type pixel data as an address to the stored gamma correction parameters.

    摘要： Provided is a system and method including a number of routers structured and arranged to route one or more video sources to any of one or more destinations. Each of the number of routers including a plurality of input and output ports and each input port being connectable to any one or more of corresponding output ports via data-paths. The datapaths are connectable to a corresponding one of the one or more destinations. The apparatus includes a testing output port selectably connectable to any of the one or more output data-paths. The testing output port is configured to connect a selected one of the one or more data-paths to a data collection device. The testing output port is configured to facilitate analysis of at least one from the group including (a) one or more of the data paths and (b) one or more of the video sources associated with the selected data-path.

    摘要： Provided is a system and method for performing CRC analysis in a video test bench. An exemplary system includes a memory configured for storing a required number representative of the data fields to be analyzed. A module is coupled at least indirectly to the memory and configured for (i) receiving an input data stream, (ii) performing cyclic redundancy check (CRC) analysis of the received data stream, and (iii) producing an output representative of an actual number of received data fields analyzed. The input data stream includes synchronization markers defining boundaries of each of the received data fields. Next, a comparator is configured for (i) comparing the required number and the actual number and (ii) producing a disabling signal when the actual number matches the required number. A detector is coupled to the comparator and configured for (i) receiving the input data stream and sensing a presence of the synchronization markers, (ii) receiving the disabling signal, and (iii) disabling the CRC module when the disabling signal is received.

    摘要： Herein described is a method and system of vertically filtering a graphics image such that an enhanced image is provided to a display. Filtering of the graphics image may be accomplished by using one or more window descriptors. The method may be implemented by computing a weighted average of one or more pixel intensities. The system may comprise a memory, a processor, and a graphics engine. The graphics engine may comprise a graphics blender. The graphics blender may comprise one or more multipliers and one or more adders. The processor may execute software resident in the memory, such that the one or more window descriptors may be used to compute the weighted average.

    摘要： A system and method, for reprogramming registers without having to reprogram unchanged registers. The registers are divided into groups based on common characteristics or functions. The values for the groups that differ from the current values are written into a linked list, which is then loaded into the appropriate registers. The linked list contains information indicating the groups of registers in the linked list.
