An Adaptive HW/SW Dual Communication Mode

HW/SW communication mode makes significant impact on HW/SW communication efficiency. Based on the characteristics of the hardware functions, this paper presents an adaptive HW/SW dual communication mode according to the traffic between the hardware and software, and builds an adaptive decision algorithm to choose HW/SW communication mode. The algorithm combining the simulated annealing and chain scheduling method to solve, the selection of HW/SW communication mode is transparent to the user. Theoretical analysis results show that the communication efficiency is optimized and the area overhead is reduced. HW/SW dual communication mode gets better in performances.
