With the miniaturization of LSIs and its increasing performance, demand for high-functional portable devices has grown significantly. At the same time, the problems for battery runtime and device overheating have occurred. On the other hand, the ratio of an interconnection delay to a gate delay has continued to increase as device feature size decreases. We have to estimate the interconnection delay and reduce energy consumption even in a high-level synthesis stage. In this paper, we propose high-level synthesis considering clock design for HDR architectures with concurrency-oriented scheduling. Firstly we focus on the number of the control steps at which we can apply the clock gating to registers and we schedule and bind operations to be performed at the same time. By adjusting the clock gating timings in a high-level synthesis stage, we enhance the effect of clock gatings than applying clock gatings after logic synthesis. Secondly, we determine the clock gating timings to minimize all energy consumption including clock tree energy. The experimental results show that our proposed algorithm reduces energy consumption by a maximum of 21.2% compared with several conventionalalgorithms. |
