A bus of 44 control signals feeds the entire DSP block. These signals
include clocks, asynchronous clears, clock enables, signed and unsigned
control signals, addition and subtraction control signals, rounding and
saturation control signals, and accumulator synchronous loads. The clock
signals are routed from LAB row clocks and are generated from specific
LAB rows at the DSP block interface. The LAB row source for control
signals, data inputs, and outputs is shown in
