摘要
在硬件资源有限的嵌入式平台上实现地图快速显示是个技术难题。针对连续地图操作时地图显示延迟的问题,本文研究了多任务模型下的消息驱动机制,运用将一个显示任务分解为一系列子任务的思想,提出了一种消息序列化的地图显示方法。实验结果表明,该方法能有效提高连续地图操作情况下的地图显示速度。
Recently,fast map display on embedded platforms with limited hardware resources has become an academic conundrum.This paper aimed at coping with the display delay of successive map display operating.Firstly,the message-drive in multitask model was studied,and then a map display method was proposed,which divided one map display task into a sequence of child-tasks.Experimental results showed that this method could efficiently speed up map display in the case of successive operating.
