svsp_rb_min_latency[14:0], Secondary VSP Map, Address 0xE6F7[7:0]; Address 0xE6F8[7:1] (Read Only)
This signal is used to read back the minimum frame/HSync latency. The upper three bits are VSync latency, the lower twelve bits are
HSync latency.

3.3.1.6. Freezing Output Video

Output video can be frozen by disabling the VIM by setting
3.3.2.

SVSP Video Input Module (VIM)

Figure 61 shows the structure of the SVSP VIM. This can be broken up into three hardware blocks. The VIM cropper can be used to crop
an input video image to a given image size. The scaler can be used to scale a video resolution to any target resolution. The pixel packer is
used to pack pixels data into memory words and write them into external memory. The starting address in external memory is provided
by FFS and is configured by the user using the frame buffer registers. As indicated at the start of
to operate, it must first be enabled. This can be done using the
output video will be frozen.

3.3.2.1. VIM Cropper

The VIM cropper block is used to define a sub window within the given input resolution. This cropped image will then become the video
which will be processed by the SVSP. The following registers are used to define this sub window.
• svsp_vim_crop_enable
• svsp_vim_crop_h_start[10:0]
• svsp_vim_crop_v_start[10:0]
• svsp_vim_crop_width[10:0]
• svsp_vim_crop_height[10:0]
To enable cropper block in VIM,
