10.5. Chroma Key IP Registers

Each register is either read-only (RO) or read-write (RW).

In the software API the register names appear with a prefix of INTEL_VVP,INTEL_VVP_CORE, or INTEL_VVP_CHROMA_KEY as appropriate and with an optional REGsuffix.

Table 61.   Control Registers
Address Register Access Description
Lite 10 Full
Parameterization registers
0x0000 PROD_ID RO RO Read this register for the Chroma Key product ID. This register always returns 0x0000_023F.
0x0004 VER RO RO Read this register to retrieve the version information for the Intel Quartus release that Intel uses to build the Chroma Key.
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 are on. This register returns 1 if reads to other registers designated as RW return the last value the IP writes to the register.
0x0010 CONSTANT_ALPHA RO RO Read this register to determine if the chroma key is operating in the constant alpha mode.
0x0014 CONSTANT_ALPHA_TAG RO RO Read this register for the value of alpha appended to pixels when operating in the constant alpha mode.

0x001C NUM_COLOR_PLANES RO RO Read this register for the number of color planes.
0x0020 PIXELS_IN_PARALLEL RO RO Read this register for the number of pixels processed each clock cycle.
Control and debug registers

For more details about these registers, refer to Control Packets

0x0120 IMG_INFO_WIDTH RW RO

For lite variants, use this register to set the expected width of the incoming video fields.

For full variants, read this register for the received width the IP derives from the image information packets.
0x0124 IMG_INFO_HEIGHT RW RO

For lite variants, use this register to set the expected height of the incoming video fields.

For full variants, read this register for the received height the IP derives from the image information packets.
0x0128 IMG_INFO_INTERLACE RW RO

For lite variants, use this register to set the expected interlace information of the incoming video fields.

For full variants, read this register for the received interlace information the IP derives from the image information packets.
0x012C RESERVED RW RO Unused
0x0130 IMG_INFO_COLORSPACE RW RO

For lite variants, use this register to set the expected color space of the incoming video fields.

For full variants, read this register for the received color space the IP derives from the image information packets.
0x0134 IMG_INFO_SUBSAMPLING RW RO

For lite variants, use this register to set the expected chroma subsampling of the incoming video fields.

For full variants, read this register for the received chroma subsampling the IP derives from the image information packets.
0x0138 IMG_INFO_COSITING RW RO

For lite variants, use this register to set the expected chroma co-siting of theincoming video fields.

0x013C IMG_INFO_FIELD_COUNT - RO The received field count field in image information packets.
0x0140 INPUT_STATUS RO RO

Bit 0: Status bit.

1 means Chroma Key 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 chroma key 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 chroma key settings via the register map until you issue a write to this register. The value you write is unimportant.
0x0148 Matched_Alpha RW RW The alpha value appended to the pixels which meet the conditions specified using the upper and lower bounds registers.
0x014C Unmatched_Alpha RW RW The alpha value appended to the pixels which do not meet the conditions specified using the upper and lower bounds registers.
0x0150 C1_Upper_Bound RW RW The upper bound of the condition for the most significant color plane.
0x0154 C2_Upper_Bound RW RW The upper bound of the condition for the center color plane.
0x0158 C3_Upper_Bound RW RW

The upper bound of the condition for the least significant color plane.

This bound is for the condition for single color plane configurations.
0x015C C1_Lower_Bound RW RW The lower bound of the condition for the most significant color plane.
0x0160 C2_Lower_Bound RW RW The lower bound of the condition for the center color plane.
0x0164 C3_Lower_Bound RW RW

The lower bound of the condition for the least significant color plane.

This bound is for the condition for single color plane configurations.
0x0168 C1_Replace RW RW The replacement value for the most significant color plane if the pixel’s condition is met.
0x016C C2_Replace RW RW The replacement value for the center color plane if the pixel’s condition is met.
0x0170 C3_Replace RW RW

The replacement value for the least significant color plane if the pixel’s condition is met.

This bound is for the replacement of single color plane configurations.
0x0174 Compare_Enable RW RW

The control bits to enable or disable comparison of the color components when operating with conditional alpha and pixel replacement.

Bit 0: enables comparison of the most significant component (C1).

It is also the comparison bit for single color plane configurations

Bit 1: enables comparison of the middle component (C2).

Bit 2: enables comparison of the least significant component (C3).
0x0178 Replace_Enable RW RW

The control bits to enable or disable replacement of the color components when operating with conditional alpha and pixel replacement.

Bit 0: enables replacement of the most significant component (C1).

It is also the replacement field for single color plane configurations.

Bit 1: enables replacement of the middle component (C2).

Bit 2: enables replacement of the least significant component (C3).
