嵌入式系统消息序列化的地图显示方法

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。

Map display method based on sequenced messages in embedded system

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.
