实时内核接口,包含内核组件和每个端口，以及一个或多个文件,具体到一个特定的微控制器或编译器。-Real time kernel interface, contains the kernel component and each port, and one or more files, specific to a particular micro controller or the compiler.

Algorithm optimization is very good, almost no circulation, It draws on principal component analysis algorithm (PCA), A one-dimensional transfer matrix method to calculate the phonon crystal structure.

Principal component analysis model for establishing, Calculated transmission characteristics and reflection characteristics of the one-dimensional photonic crystals, There ULA CRB curve.
