12.4. Clipper IP Registers

Table 119.   Control Registers In the software API the register names appear with a prefix of INTEL_VVP, INTEL_VVP_CORE or INTEL_VVP_CLIPPER as appropriate and with an optional REG suffix
Address Register Access Description
Lite 17 Full
Parameterization registers
0x0000 VID_PID RO RO

Read this register for the clipper product ID.

This register always returns 0x6AF7_022D.

0x0004 VERSION RO RO

Read this register for the version information for the Intel Quartus release that Intel uses to build the clipper.
0x0008 LITE_MODE RO RO

Read this register to determine if Lite mode is on or off.

This register returns 0 when Lite mode is off and 1 when on.

0x000C DEBUG_ENABLED RO RO

Read this register to determine if Debug features is on.

0x0010 CLIPPING_MODE RO RO Read this register to determine the Clipping method
0x0014 to 0x011F Unused.
Control and debug registers 18
0x0120 IMG_INFO_WIDTH RW RO For lite designs, the expected width of the incoming video fields. For full, the received width in the IP derives from the image information packets.
0x0124 IMG_INFO_HEIGHT RW RO For lite designs, the expected height of the incoming video fields. For full the received height in the IP derives from the image information packets.
0x0128 IMG_INFO_INTERLACE RW RO For lite designs, the expected interlace information of the incoming video fields. For full, the received interlace information in image information packets.
0x012C Reserved - - Reserved.
0x0130 IMG_INFO_COLORSPACE RW RO For lite designs, the expected color space of the incoming video fields. For full, the received color space in image information packets.
0x0134 IMG_INFO_SUBSAMPLING RW RO For lite designs, the expected chroma subsampling of the incoming video fields. For full, the received chroma subsampling in image information packets.
0x0138 IMG_INFO_COSITING RW RO For lite designs, the expected chroma co-siting of the incoming video fields. For full, the received chroma co-siting in image information packets.
0x013C IMG_INFO_FIELD_COUNT - RO The received field count field in image information packets.
0x0140 STATUS RO RO

Bit 0: status bit.

1 = clipper is processing a video field, 0 otherwise.

Full designs only:

Bit 1: Pending register updates bit.

Any writes to the clipping specification registers (0x0148 - 0x0154) cause the pending register updates bit to be raised, to indicate outstanding changes to the clipping settings.

The IP lowers this bit at the start of the first packet for a new frame (first packet after the EOP packet) after a write to the COMMIT register.

0x0144 COMMIT RW RW

The IP uses this register with the STATUS register pending register updates bit.

Write any value to this register after writing new values to any of the clipping specification registers (0x0148 - 0x0154). The clipper switches to the new clipping specification values at the start of the next video frame after you write to this register.

The commit register ensures atomic register updates, avoiding the IP only applying some of the updated register values for the next incoming frame.

Clipping specification registers
0x0148 LEFT_OFFSET RW RW

If you select Clipping with offsets, write to this register to set the required offset from the left edge of the video.

If you select Clipping with output dimensions, this offset defines the offset from the left edge of the video for top left corner of the clipped output.

0x014C TOP_OFFSET RW RW

If you select Clipping with offsets, write to this register to set the required offset from the top edge of the video.

If you select Clipping with output dimensions, this offset defines the offset from the top edge of the video for the top left corner of the clipped output.

0x0150 RIGHT_OFFSET/CLIP_WIDTH RW RW

If you select Clipping with offsets, write to this register to set the required offset from the right edge of the video.

If you select Clipping with output dimensions, write to this register to set the required width of the output video.

0x0154

BOTTOM_OFFSET/CLIP_HEIGHT

RW RW

If you select Clipping with offsets, write to this register to set the required offset from the bottom edge of the video.

If you select Clipping with output dimensions, write to this register to set the required height of the output video.
