摘要
为了支持通用系统的功耗建模 ,提出一种以健壮性为目标的 RT级瞬时功耗建模方法 ,即在特定的误差限制下 ,可以适用于更多的应用情况。对于一个给定的电路模块 ,首先构造反映电路结构特征的启发式函数进行功耗分类 ,对每个分类采用常数标识功耗 ;然后对启发式进行组合 ,进一步提高功耗模型的健壮性。从实验结果来看 ,健壮性比已有的功耗模型提高了 1 0 %到 2 0 %。
To support the power modeling of the general purpose system, a robustness targeted power modeling method is presented, which can adapt to more conditions under given error limits A heuristic function for special circuit structure is constructed to classify the power samples Subsequently, each class is marked with a constant power estimate, and the heuristic functions are combined for further robustness improvement Compared with the existing power model, the experiment shows significant improvement on robustness from 10% to 20%
