摘　　要：软硬件通信模式的选择对软硬件通信效率产生很大影响.根据硬件函数的特点,提出一种根据软硬件通信量自适应地选择通信模式的软硬件双通信模式,并构建了一种通信模式自适应决策算法,软硬件通信模式的选择对用户透明.实验表明,根据运行时系统状态自适应地选择通信模式,软硬件通信效率得到优化,面积开销也适当减少.HW/SW communication mode makes a significant impact on the efficiency of HW/SW communication. Based on the characteristics of the hardware function, presents a self-adaptive HW/SW dual communication mode according to the traffic between the hardware and software, and builds an adaptive decision algorithm to choose communication mode, the selection of HW/SW communication mode is transparent to the user. Experiment results shows that according to adaptive run-time system state to select communication mode, HW/SW communication efficiency is optimized and the area overhead is reduced.
