内存使用量

通过生成的代码优化 RAM、ROM 和堆栈空间的使用

可以通过以下方法控制内存消耗：指定代码生成器将变量定义为局部变量或全局变量，以及指定数据如何传递给子系统函数。修改配置设置以减少用于存储数据的内存量。

代码生成器通过合并控制流构造、删除不影响计算结果的模块的无效代码路径和代码来减少 ROM 消耗。您可以通过删除可能不需要的代码（如初始化代码、重置和禁用函数以及防御性代码）来进一步减少 ROM 消耗。

Vector Operation Optimization
The code generator reduces stack memory by replacing temporary local arrays with local variables.
Reduce Memory Usage for Boolean and State Configuration Variables
Reduce the amount of memory that stores state configuration variables and Boolean variables.
Optimize Generated Code Using memset Function
The memset function clears internal storage, regardless of type, to the integer bit pattern 0 (that is, all bits are off).
Customize Stack Space Allocation
Control the maximum allowable stack size to provide some control over whether data is defined locally or globally in the generated code.
Configure Loop Unrolling Threshold
Starting at a default value of 5, the code generator begins to use a for loop instead of separate statements to assign values to the elements of a signal or parameter array.
Specify Single-Precision Data Type for Embedded Application
Generate code whose floating-point data types are only single precision, for example, for targeting a single-precision processor.
Generate Efficient Code by Specifying Data Types for Block Parameters
To generate more efficient code, match parameter data types with signal data types or store parameters in smaller data types.
Optimize Generated Code Using Boolean Data for Logical Signals
The code generator optimizes the generated code by storing logical signals as Boolean data types.
优化时间计数器的内存使用量
优化代码生成器为经过时间计数器分配的内存。
