Relative Control Optimization
The control implementation resulting from relative control synthesis can be optimized further to reduce its size. Control optimization can be performed either at the logic level by using a finite-state machine model [MSBSV90, SDP90] or at a higher level by using a hardware model described in terms of constraints on the sequencing and timing of the operations [Wo190, DM92]. In the former case, the operations are bound to control states. This implies that the cycle-per-cycle behavior of the control cannot be altered without changing the control specification. Techniques such as sequential logic synthesis and microcode compaction can be used to reduce the cost of the control implementation [GRVD87].
