Parameter Value Description
General
Convert from signed to unsigned
by
• Saturating to
minimum value at
stage 4
• Replacing negative
with absolute value
Select the method of signed to unsigned
conversion for the results.
Operands
Run-time control 32–4096,
Default = 1920 Turn on to enable run-time control of the
conversion values.
Coefficient and summand
fractional bits
0–34, Default = 8 Specify the number of fraction bits for the
fixed point type used to store the coefficients
and summands.
Coefficient precision: Signed On or Off Turn on to set the fixed point type used to
store the constant coefficients as having a
sign bit.
Coefficient precision: Integer
bits
0–16,
Default = 10 Specifies the number of integer bits for the
fixed point type used to store the constant
coefficients.
Summand precision: Signed On or Off Turn on to set the fixed point type used to
store the constant summands as having a sign
bit.
Summand precision: Integer bits 0–22,
Default = 10
Specifies the number of integer bits for the
fixed point type used to store the constant
summands.
Color Space Conversion Signals
Table 10-3: Color Space Conversion Signals
The table below lists the signals for Color Space Converter and Color Space Converter II IP cores.
Signal Direction Description
reset
Input The IP core asynchronously resets when you assert this
signal. You must deassert this signal synchronously to the
rising edge of the clock signal.
clock
Input The main system clock. The IP core operates on the rising
edge of this signal.
din_data
Input
din
port Avalon-ST
data
bus. This bus enables the
transfer of pixel data into the IP core.
