11.4. Chroma Resampler IP Registers

Each register is either read-only (RO) or read-write (RW).
Table 96.   Parameterization registers In the software API the register names appear with a prefix of INTEL_VVP, INTEL_VVP_CORE or INTEL_VVP_CRS as appropriate and with an optional REG suffix
Address Register Access Description
0x0000 VID_PID RO

Read this register to retrieve chroma resampler product ID.

This register always returns 6AF7_022E

0x0004 VERSION RO

Read this register to retrieve the version information for the Intel Quartus release that Intel uses to build the chroma resampler.

0x0008 LITE_MODE RO Read this register to determine if lite mode is on. This register returns 0 when you turn off lite and 1 when you turn on lite.
0x000C DEBUG_ENABLED RO Read this register to determine if debug features is on. This register returns 1 if reads to other registers designated as RW return the last value the IP writes to the register, or an undefined value.
0x0010 ENABLE_444 RO Read this register to determine if 4:4:4 chroma sampling is supported at the output.
0x0014 ENABLE_422 RO Read this register to determine if 4:2:2 chroma sampling is supported at the output.
0x0018 ENABLE_420 RO Read this register to determine if 4:2:0 chroma sampling is supported at the output.
0x0060 to 0x011F - - Unused.
Table 97.   Control and debug registers For more information, refer to Control Packets. You must turn on debug features to read the values stored in these registers. If you turn off debug features, reads to these registers return undefined data. The only exception is the STATUS register, the value of which you can always read
Address Register Access Description
Lite Full
0x0120 IMG_INFO_WIDTH RW RO

When you turn on lite, use this register to set the expected width of incoming video fields.

When you turn off lite and turn on Debug features, this register returns the width that the chroma resampler derives from information in the image information packet.

0x0124 IMG_INFO_HEIGHT RW RO

When you turn on lite, use this register to set the expected height of incoming video fields.

When you turn off lite and turn on Debug features, this register returns the height that the chroma resampler derives from information in the image information packet.

0x0128 IMG_INFO_INTERLACE - RO When you turn off lite and turn on Debug features, this register returns the interlace nibble that the chroma resampler derives from information in the image information packet.
0x012C Reserved - - Reserved
0x0130 IMG_INFO_COLORSPACE - RO When you turn off lite and turn on Debug features, this register returns the color space that the chroma resampler derives from information in the image information packet.
0x0134 IMG_INFO_SUBSAMPLING RW RO

When you turn on lite, use this register to set the expected chroma sampling of incoming video fields.

When you turn off lite and turn on Debug features, this register returns the subsampling that the chroma resampler derives from information in the image information packet.

0x0138 IMG_INFO_COSITING - RO When you turn off lite and turn on Debug features, this register returns the cositing that the chroma resampler derives from information in the image information packet.
0x013C IMG_INFO_FIELD_COUNT - RO When you turn off lite and turn on Debug features, this register returns the field count that the chroma resampler derives from information in the image information packet.
0x012C to 0x013C - - - Unused.
0x0140 STATUS RO

Bit 0 : Status bit.

1 means chroma resampler is processing a video field, 0 otherwise.

When you turn off Lite mode:

Bit 1 : Pending register updates bit.

Any writes to the output sampling register (0x0148) cause the IP to raise the pending register updates bit, to indicate outstanding changes to the resampling settings.

The IP lowers this bit at the next field boundary after a write to the COMMIT register.

0x0144 COMMIT RW Only when you turn off lite mode. The IP holds any changes to the scaling settings (not coefficients) via the register map until you issue a write to this register. The value you write is unimportant.
0x0148 OUTPUT_MODE RW Write to this register to set the output chroma sampling. Write 0 for 4:2:0, 2 for 4:2:2 and 3 for 4:4:4
