+Data-flow dependencies that can be discovered using a
+<span class="spurious-link" target="*Data-flow Graph">*data-flow
+graph*</span> are useful for high-level synthesis optimisations, as
+instructions that do not depend on each other can be scheduled into the
+same clock cycle. However, in addition to that, even if there is a data
+dependency between two operations, but the operations can both be
+completed faster than the time required for the clock cycle, then these
+can be scheduled into the same clock cycle as well.
+
+This allows for less registers in the hardware that need to store
+intermediate results, and can also lead to less states and reduce the
+throughput of the circuit.
