High-Level Optimizations Square Root Example
After optimizations to reduce
complexity of required operators:
Notes:
The dataflow graph for the control mechanism uses simpler functional nodes than the first version by replacing a general-purpose relational operator with a =0 check and an adder with an incrementer.
The dataflow graph for the data calculations replaces the multiply-by-0.5 with a simple binary shift.
The dataflow graph on the far right instantiates multiple copies of the simpler data calculations dataflow graph in order to avoid having to include the control dataflow graph nodes.
