....the synthesis systems described above worked primarily on datapath dominated circuits where the effect of control nodes was negligible. Many researches have attempted to relax this assumption and proposed high level synthesis systems towards control dominated designs [32] 33] 34] 28] 29] [13]. The most notable work towards providing synthesizability for control intensive designs is IMPACT [70] which is geared for power optimization. Their methodology is also based on SCALP with some generalizations for handling control. They use behavioral simulation to generate traces and statistics ....

....is to further optimize the (relatively small) common case behavior aggressively using known power and performance optimization techniques. Since the common case operations extracted from the schedule are represented at the behavior level, a natural choice is to use behavioral transformations [9, 10, 13, 14] to simplify them. We use a powerful transformation framework to apply various transformations aimed at minimizing the number of operations, and the critical path, of the common case behavior. For the GCD example, the initial common case behavior shown in Figure 2(a) is automatically transformed ....
....only for its generation, thus simplifying the behavior. Step 5 derives the common case execution circuit. In this step, optimizing transformations are applied to simplify the common case behavior, prior to synthesis. Power optimizing transformations have been extensively studied in the literature [10, 13, 14]. Performanceoptimizing transformations can also be used at this point [9] At the end of this step, the simplicity of the common case circuit can be assessed. We also have sufficient information to estimate the power and execution time savings obtainable from the chosen pattern. Step 6 performs ....
