YCrCb 4:4:4. This IP has an AXI4 slave interface to configure, control, and read status from
the application software.
For detailed information on the complete feature set, a functional description, and license
information for Chroma Resampler, see the LogiCORE IP Chroma Resampler Product Guide
(PG012) [Ref 9].
YCrCb to RGB Color-Space Converter
Instance: system_top_i/Video_Capture/YUV2RGB_0
This IP is a color space converter, which converts the video from YCrCb to RGB format as the
rest of video IPs in the pipeline work on RGB video. This IP has an AXI4 slave interface to
configure, control, and read status from the application software.
For detailed information on the complete feature set, a functional description, and license
information for YCrCb to RGB Color-Space Converter IP, see the LogiCORE IP YCrCb to RGB
Color-Space Converter Product Guide (PG014)
Video Multiplexer
Instance: system_top_i/Video_Capture/VIDEO_MUX_0
This IP multiplexes the sync signals from time base generator (VTC_0) and
fmc_imageon_hdmi_in and feeds the Video In to AXI4-Stream (VID_IN_AXI4S). The selection
is done by PS GPIO (ps7_0_GPIO_O[3]).
For detailed information on the complete feature set and a functional description of Video
in to AXI4-Stream IP, see the LogiCORE IP Video In to AXI4-Stream v1.0 (PG043)
Sobel Filter
Instance: system_top_i/Video_Processing/FILTER_ENGINE
This IP has the AXI4-Lite interface through which the IP is configured and controlled.
The number of rows and columns are configured using AXI interface, and the filtering
process starts when the Start register is written through the Sobel interface.
The Sobel filter detects the edge in the video frame and the processed frame is sent out on
AXI stream interface.
