The SVSP can be used to offer the option of a second output resolution to the user. The structure of the SVSP is similar to the PVSP but it
is much simpler in design and does not contain all the processing elements of the PVSP. The structure of the SVSP comprises FFS, VIM,
and VOM blocks.
Input to the SVSP can only be in progressive format.
The SVSP has the following features:
•
Image cropping
•
Scaling
•
FRC
•
PtoI conversion
The image cropping function is the same as that provided in the PVSP and, like the PVSP, there is an image cropper in both the VIM and
the VOM of the SVSP. In the SVSP only, the VIM is capable of scaling video data. This means that the VIM of the SVSP can support
vertical resolution scaling as well as horizontal resolution scaling.
The SVSP is also capable of performing FRC, which is controlled by the FFS of the SVSP. The FFS in the SVSP provides the same
functionality as the FFS in the PVSP. A PtoI converter which can be used to convert the incoming video standard from progressive to
interlaced is also included as part of the SVSP.
Like game mode in PVSP, SVSP can also support bypass DDR mode. Using this mode, the SVSP can convert between 1080p and 720p
without using external memory. This allows the user to perform a simple conversion which does not use external memory bandwidth.
However, FRC is not supported in this case.
The SVSP can be simply bypassed by setting
to 1.
Note:
The input to the SVSP can only be progressive video. Therefore, interlaced video must be routed through the de-interlacer in the
PVSP before being routed to the SVSP. The PVSP output can also be sent to the SVSP as a progressive input.
svsp_bypass
, Secondary VSP Map,
Address 0xE649[6]
This bit is used to bypass the Secondary VSP.
Function
svsp_bypass
Description
0
Not bypass Secondary VSP
1
Bypass Secondary VSP
Similarly, if using the SVSP, the VIM and VOM must be enabled. This can be done by enabling
svsp_enable_vim
, Secondary VSP Map,
Address 0xE610[6]
This bit is used to control the Video Input Module (VIM). If this bit is set to 1, the VIM is enabled to write packed input video data into
the defined external frame buffer. While the Secondary VSP is running, if this bit is set to 0, the output video stream will be frozen.
Function
svsp_enable_vim
Description
0
Disable VIM
1
Enable VIM
