Patent number: 7149954Abstract: 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.Type: GrantFiled: August 25, 2003Date of Patent: December 12, 2006Assignee: Broadcom CorporationInventors: Darren Neuman, Chengfuh Jeffrey Tang, Yao-Hua Steven Tseng, Guang Ting Shih, Wen Huang, Charles Thomas Monahan

Publication number: 20050179697Abstract: Aspects of the invention may include a method updating a color look-up table (CLUT) for a next line of graphics before a current line of graphics has been completely read out of a graphics FIFO and assigned color pixel values. The method may include the step of formatting or arranging the CLUT into a plurality of sub-CLUTs. Each one of the sub-CLUTs may include pixel color values for each one of a plurality of pixels which may include a line of the graphics image data. Pixel color values may be read from within a first selected sub-CLUT, the first selected sub-CLUT comprising pixel color values for a first line of the graphics image data. The read pixel color value may be applied to the current first line of the graphics image data. While the read pixel color value is being applied to the current first line, pixel color values for a second selected sub-CLUT may be updated. The second selected sub-CLUT may include color pixel values for a second line of the graphics image data.Type: ApplicationFiled: September 30, 2004Publication date: August 18, 2005Inventors: Guang-Ting Shih, Jay Li, Steven Tseng, Chengfuh Tang

Publication number: 20040034641Abstract: A method and system are disclosed for decimating an indexed set of data elements to generate a decimated set of data elements. The indexed set of data elements are grouped into groups of at least two data elements per group. The indexes of the data elements in each group are used to address a look-up-table (LUT) that is pre-programmed to perform the decimation operation. For each group of data elements presented to address the LUT, a decimated data value is output from the LUT. The decimated data value is a function of the data values of the corresponding data elements addressing the LUT.Type: ApplicationFiled: August 13, 2002Publication date: February 19, 2004Inventors: Steven Tseng, Chris Tsang
