Optimizer

A number of optimizations were implemented in order to generate efficient hardware. Perhaps the most important of these is loop-unrolling, which can replace sequential circuitry with combinational logic when successful. In order to recognize when unrolling is possible, constant propagation and folding are done. Constant propagation, constant folding, and dead code elimination also reduce the amount of unnecessary hardware generated.

• Static Single-Assignment Form
• Conditional Constant Propagation
