Power gating is well-known technique to reduce the leakage energy drastically, but it suffers from performance penalty. This research proposes leakage energy aware HW/SW co-design method for fine-grained power gated VLIW processors. VLIW processors have multiple instruction slots, and power gating is supposed to be applied to each functional units. This research proposes two methods: energy-aware instruction scheduling method and architecture exploration method. Energy-aware instruction scheduling method optimizes the instruction scheduling taking into account power gating effects. Architecture exploration method tries to find Pareto optimal architecture candidates, and especially focuses on the number of functional unit and instruction assignment. Experimental results show the efficiency of proposed methods.

功率门控是众所周知的可大幅减少泄漏能量的技术，但它会受到性能损失。本研究提出了针对细粒度功率门控 VLIW 处理器的泄漏能量感知硬件/软件协同设计方法。 VLIW处理器具有多个指令槽，并且电源门控应该应用于每个功能单元。本研究提出了两种方法：能量感知指令调度方法和架构探索方法。能量感知指令调度方法考虑功率门控效应来优化指令调度。架构探索方法试图找到帕累托最优架构候选者，特别关注功能单元的数量和指令分配。实验结果表明了所提出方法的有效性。
