Abstract(in English) | To synthesize high performance VLSI systems, the importance of exploiting interconnection delay information at higher level design is recognized. To improve system performance further in terms of total computation time and/or robustness to delay variation, we are going to introduce appropriate delays which differentiate the arrival times of control signals to registers. A similar technique to the skew of flip-flop control has been proposed for sequential circuits, and significant effort has been devoted to so-called clock scheduling. There is a difference that, in general, clock signal in a sequential circuit is fed to each register every time, while register control signal in RT level datapath is fed to a register only in selected (i.e., scheduled) control steps. When we comprehend the behavior of a datapath with data flows instead of executions of operations, a multiplexer in a datapath behaves as a gate starting and stopping data flow. Introduction of the skew in the arrival times of control signals to multiplexers will contribute, as well as the one for registers, to improve system performance. In this paper, we propose optimization algorithm of skew for both registers and multiplexers in placed RT level datapath. |
