Core Interfaces and Register Spacebe useful to identify external memory / Frame buffer / or throughput bottlenecks in a videosystem. Refer to Debugging Features in Appendix C for more information.SYSDEBUG1 (0x0018) RegisterThe SYSDEBUG1, or Line Throughput Monitor, register indicates the number of linesprocessed since power-up or the last time the core was reset. The SYSDEBUG registers canbe useful to identify external memory / Frame buffer / or throughput bottlenecks in a videosystem. Refer to Debugging Features in Appendix C for more information.SYSDEBUG2 (0x001C) RegisterThe SYSDEBUG2, or Pixel Throughput Monitor, register indicates the number of pixelsprocessed since power-up or the last time the core was reset. The SYSDEBUG registers canbe useful to identify external memory / Frame buffer / or throughput bottlenecks in a videosystem. Refer to Debugging Features in Appendix C for more information.ACTIVE_SIZE (0x0020) RegisterThe ACTIVE_SIZE register encodes the number of active pixels per scan line and thenumber of active scan lines per frame. The lower half-word (bits 12:0) encodes the numberof active pixels per scan line. Supported values are between 32 and the value provided inthe Maximum number of pixels per scan line field in the GUI. The upper half-word (bits28:16) encodes the number of active scan lines per frame. Supported values are 32 to 7680.To avoid processing errors, the user should restrict values written to ACTIVE_SIZE to therange supported by the core instance.YMAX (0x0100) RegisterThe YMAX register holds the maximum value allowed on the Luma (Y) channel of theoutput. If the output data is greater than this value, then this value replaces it on the output.This register is only valid if Outputs Clipped is selected in the core parameterization GUI.YMIN (0x0104) RegisterThe YMin register holds the minimum value allowed on the Luma (Y) channel of the output.If the output data is less than this value, then this value replaces it on the output. Thisregister is only valid if Outputs Clipped is selected in the core parameterization GUI.CbMax (0x0108) RegisterThe CbMAX register holds the maximum value allowed on the Cb Chroma channel of theoutput. If the output data is greater than this value, then this value replaces it on the output.This register is only valid if Outputs Clipped is selected in the core parameterization GUI.RGB to YCrCb Color-Space Converter www.xilinx.com 20PG013 April 24, 2012Product Specification
