Abstract(in English) | As well as the schedule affects system performance, the control skew, i.e., the arrival time difference of control signals between registers, can be utilized to improve the system performance. In this paper, we discuss the simultaneous optimization of the control step assignment and the control skew assignment, and we prove that, even if the execution sequence of operations assigned to the same resource is fixed and only the control step assignment remains unfixed, the simultaneous optimization problem under a fixed clock period is NP-hard. The proof is based on the reduction from 3SAT problem. The result of this paper would become an important base for various types of the intentional-skew-aware system optimization problems. |
