16.2. Color Space Converter IP Parameters

Table 223.  Color Space Converter IP Parameters - General Tab
Parameter Value Description
Control Settings
Memory-mapped control interface On or off Turn on to specify Color Space Converter register values using the Avalon memory-mapped interface.
Separate clock for control interface On or off Turn on for a separate clock for the control interface.
Debug features On or off Turn on for debugging features (not applicable for lite mode).
Pipeline ready signals On or off Turn on to pipeline ready signals, which helps with improving Fmax.
Video Data Format
Lite mode On or off Turn on to operate the Color Space Converter in lite mode.
Input bits per color sample 8 to 16 Select the number of input bits per color sample.
Output bits per color sample 8 to 16 Select the number of output bits per color sample.
Number of pixels in parallel 1 to 8 Select the number of pixels in parallel.
Output Color space RGB, YCbCr, or MONO Only applies if Memory-mapped control interface and Lite mode are off. Use this to set the color space field value of outgoing image information packets. It does not affect the algorithmic values, only the metadata.
Table 224.  Color Space Converter IP Parameters - Operands Tab
Parameter Allowed range Description
Properties
Coefficient and summand fractional bits 0 to 24 Specify the number of fraction bits for the fixed-point type to store the coefficients and summands.
Coefficient precision: Signed On or Off Turn on to set the fixed-point type to store the constant coefficients as having a sign bit.
Coefficient precision: Integer bits 0 to 16 Specifies the number of integer bits for the fixed-point type to store the constant coefficients.
Summand precision: Signed On or Off Turn on to set the fixed-point type to store the constant summands as having a sign bit.
Summand precision: Integer bits 0 to 20 Specify the number of integer bits for the fixed-point type used to store the constant summands.
Result to output data type conversion
Move binary point right

-16 to +16

Specify the number of places by which to move the binary point to the right. Negative numbers indicate moving the binary point to the left.
Remove fraction bits by
  • Round values - Half up
  • Round values - Half even
  • Truncate values to integer
Select the method of discarding fraction bits resulting from the calculation.

Coefficients and Summand

Table

A0, B0, C0, S0

A1, B1, C1, S1

A2, B2, C2, S2

12 fixed-point values Only when you turn off Memory-mapped control interface. Each coefficient or summand is represented by a white cell with a gray cell underneath. The value in the white cell is the desired value and is editable. The value in the gray cell is the actual value, determined by the fixed-point type specified. The gray cells are not editable. You can create a custom coefficient and summand set by specifying one fixed-point value for each entry.
