svsp_vim_crop_width[12:0] , Secondary VSP Map, Address 0xE61E[7:0]; Address 0xE61F[7:3]
This signal is used to set the input width of the VIM cropper.
Function
svsp_vim_crop_width[12:0] Description
0x000 (default) Default
0xXXX Width of VIM cropper input
svsp_vim_crop_height[12:0] , Secondary VSP Map, Address 0xE620[7:0]; Address 0xE621[7:3]
This signal is used to set the input height of the VIM cropper.
Function
svsp_vim_crop_height[12:0] Description
0x000 (default) Default
0xXXX Height of VIM cropper input
Note: The following limitations apply to the values that can be programmed in these registers:
•
Register values programmed must be even numbers
•
0 <= svsp_vim_crop_h_start[12:0] <= (INPUT VIDEO HORIZONTAL RESOLUTION – 1)
•
0 <= svsp_vim_crop_v_start[12:0] <= (INPUT VIDEO VERTICAL RESOLUTION – 1)
•
( svsp_vim_crop_h_start[12:0] + svsp_vim_crop_width[12:0] ) <= INPUT VIDEO HORIZONTAL ACTIVE PIXELS
•
( svsp_vim_crop_v_start[12:0] + svsp_vim_crop_height[12:0] ) <= INPUT VIDEO VERTICAL ACTIVE PIXELS
3.3.2.2. Scaler
The size of the active image being sent to the SVSP is configured using svsp_vim_crop_height[12:0] and svsp_vim_crop_width[12:0] as
mentioned in Section 3.3.2 . The output of the SVSP scaler can be set using svsp_vim_scal_out_height[10:0] and svsp_vim_scal_out_width[10:0] ,
or it can be automatically set per svsp_autocfg_output_vid[7:0] . These registers should be set to the resolution of the output video.
svsp_man_scal_out_enable , Secondary VSP Map, Address 0xE662[5]
This bit is used to enable manually setting scaler output resolution.
Function
svsp_man_scal_out_enable Description
0 (default) Disable
1 Enable
svsp_vim_scal_out_height[10:0] , Secondary VSP Map, Address 0xE624[7:0]; Address 0xE625[7:5]
This signal is used to set the output vertical resolution of scaler in the VIM.
Function
svsp_vim_scal_out_height[1
0:0]
Description
0x000 (default) Default
0xXXX Output height of VIM scaler
svsp_vim_scal_out_width[10:0] , Secondary VSP Map, Address 0xE622[7:0]; Address 0xE623[7:5]
This signal is used to set the output horizontal resolution of scaler in the VIM.
Function
svsp_vim_scal_out_width[10:
0]
Description
0x000 (default) Default
0xXXX Output width of VIM scaler
