优化生成的代码通过包装布尔数据为本
这个例子展示了如何优化生成的代码通过包装布尔数据为本。当您选择模型配置参数包布尔数据为本,嵌入式编码器®包本布尔信号比特,减少内存消耗。默认情况下,启用了优化。这种优化减少了内存消耗。请注意,这种优化可以增加代码大小和执行速度。
示例模型
考虑到模型rtwdemo_pack_boolean。
模型=“rtwdemo_pack_boolean”;open_system(模型);
禁用优化
打开配置参数对话框。
在优化>信号和参数窗格中,清晰的包布尔数据为本。
或者,您可以使用命令行API禁用优化:
set_param(模型,“BooleansAsBitfields”,“关闭”);
创建一个临时文件夹(在你的系统临时文件夹)的构建和检验过程。
currentDir = pwd;[~,cgDir] = rtwdemodir ();
没有生成代码优化
使用嵌入式程序员®构建模型。
rtwbuild(模型)

启用优化
打开配置参数对话框。
在优化>信号和参数窗格中,选择包布尔数据为本。
或者,您可以使用命令行API启用优化:
set_param(模型,“BooleansAsBitfields”,“上”);
生成代码的优化
使用嵌入式程序员®构建模型。
rtwbuild(模型)

选择包布尔数据为本使模型配置参数设置说明符类型说明符。进一步优化代码,选择uchar_t。然而,优化的好处设置说明符类型说明符设置取决于你所选择的目标。
关闭模型和代码生成报告。
bdclose rtwdemoclean(模型);cd (currentDir)
