    Parameters

    Name Type Range Default Description
    work_mode unsigned 0 for Pipeline, 1 for Req-ack 0 This module's working mode.
    data_width unsigned None 8 Data bit width.
    im_width unsigned 1 - 4096 320 Width of image.
    im_height unsigned 1 - 4096 240 Height of image.
    im_width_bits unsigned Depend on width of image 9 The bits of width of image.

    Ports

    Name Port Type Range Default Description
    clk input unsigned None None Clock.
    rst_n input unsigned None None Reset, active low.
    offset_x input signed The value must be true code if offset is positive, if negative, must be complemental code. None Offset for horizontal.
    offset_y input signed The value must be true code if offset is positive, if negative, must be complemental code. None Offset for vertical.
    in_enable input unsigned None None Input data enable, in pipeline mode, it works as another rst_n, in req-ack mode, only it is high will in_data can be really changes.
    in_data input unsigned data_width - 1 : 0 None Input data, it must be synchronous with in_enable.
    in_count_x input unsigned im_width_bits - 1 : 0 None Input pixel count for width.
    in_count_y input unsigned im_width_bits - 1 : 0 None Input pixel count for height.
    out_ready output unsigned None None Output data ready, in both two mode, it will be high while the out_data can be read.
    out_data output unsigned data_width - 1 : 0 None Output data, it will be synchronous with out_ready.
    out_count_x output unsigned im_width_bits - 1 : 0 None Output pixel count for height.
    out_count_y output unsigned im_width_bits - 1 : 0 None Output pixel count for height.

    Timing

    512x512, width of color is 8.

    The max Data Path Delay is 2.113ns, so:

    FMax = 473.26MHz
