MULTADDSUBSUM sysDSP Element
In this case, the operands A0 and B0 are multiplied and the result is added/subtracted with the result of the multi-
plier operation of operands A1 and B1. Additionally the operands A2 and B2 are multiplied and the result is added/
subtracted with the result of the multiplier operation of operands A3 and B3. The result of both addition/subtraction
are added in a summation block. The user can enable the input, output and pipeline registers. Figure 2-23 shows
the MULTADDSUBSUM sysDSP element.

Clock, Clock Enable and Reset Resources
Global Clock, Clock Enable (CE) and Reset (RST) signals from routing are available to every DSP block. From four
clock sources (CLK0, CLK1, CLK2, CLK3) one clock is selected for each input register, pipeline register and output
