17.4. Deinterlacer Registers
Register Bit Descriptions
In the software API the register names appear with a prefix of INTEL_VVP, INTEL_VVP_CORE, or INTEL_VVP_ DEINTERLACER as appropriate and with an optional REG suffix.
Address | Register | Access | Description | |
---|---|---|---|---|
Lite 42 | Full | |||
Parameterization registers | ||||
0x0000 | PROD_ID | RO | RO | Read this register for the Deinterlacer product ID. This register always returns 0x0000_023A. |
0x0004 | VER | RO | RO | Read this register for the version information for the Intel Quartus release that Intel uses to build the Deinterlacer. |
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 | MAX_WIDTH | RO | RO | Read this register to determine the maximum supported frame width. |
0x0014 | DIL_MODE | RO | RO | Read this register to determine the deinterlacing algorithm. Currently always returns 0, representing the ‘bob’ algorithm. |
0x0018 | BOB_DIL_MODE | RO | RO | Read this register to determine the Bob deinterlacing mode. Returns 0 if deinterlacing F0 fields only, returns 1 if deinterlacing F1 fields only, otherwise returns 2. |
Control and debug registers For more information, refer to Control Packets |
||||
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 | RW | RO | Unused. |
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 | INPUT_STATUS | RO | RO | Bit 0: input status bit. 1 = Deinterlacer is receiving and processing a video field, 0 otherwise. |

Name | Bits | Description |
Max width | 31:0 | This register returns the maximum supported frame width. |
Name | Bits | Description |
Deinterlacer mode | 31:0 | Currently returns 0, indicating the IP is using a bob algorithm. |
Name | Bits | Description |
Bob deinterlacer mode | 31:0 | This register returns the ob deinterlacing mode. Returns 1 if deinterlacing F0 fields only, returns 2 if deinterlacing F1 fields only, otherwise returns 3. |
Name | Bits | Description |
Width bits | 15:0 | When you turn on lite mode, write to this register to set the expected width of the incoming video fields. When you turn off lite mode and turn on Debug features, this register returns the width-1field from the most recently received image information packet and adds 1 to return a value for width. |
unused | 31:16 | Unused. |
Name | Bits | Description |
Height bits | 15:0 | When you turn on lite mode, write to this register to set the expected height of the incoming video fields. When you turn off lite mode and turn on Debug features, this register returns the height-1fieldfrom the most recently received image information packet and adds 1 to return a value for height. |
unused | 31:16 | Unused. |
Name | Bits | Description |
InterlaceNibble bits | 3:0 |
When you turn on lite mode, write to this register to set the expected interlacing of the incoming video fields:
When you turn off lite mode and turn on Debug features, this register returns the intlaceNibblefield from the most recently received image information packet. |
unused | 31:4 | Unused. |
Name | Bits | Description |
CSPcode bits | 6:0 | When you turn on lite mode, write to this register to set the expected color space of the incoming video fields. When you turn off lite mode and turn on Debug features, this register returns the 7 bit CSP field from the most recently received image information packet. |
