Clock, Clock Enable and Reset Resources
Global Clock, Clock Enable and Reset signals from routing are available to every DSP block. Four Clock, Reset
and Clock Enable signals are selected for the sysDSP block. From four clock sources (CLK0, CLK1, CLK2, CLK3)
one clock is selected for each input register, pipeline register and output register. Similarly Clock enable (CE) and
Reset (RST) are selected from their four respective sources (CE0, CE1, CE2, CE3 and RST0, RST1, RST2, RST3)
at each input register, pipeline register and output register.
Signed and Unsigned with Different Widths
The DSP block supports different widths of signed and unsigned multipliers besides x9, x18 and x36 widths. For
unsigned operands, unused upper data bits should be
fi
lled to create a valid x9, x18 or x36 operand. For signed
two’s complement operands, sign extension of the most signi
fi
cant bit should be performed until x9, x18 or x36
width is reached. Table 2-8 provides an example of this.
