Code execution profiler that collects timing information for generated code

Description

AProfilerobject that specifies the code execution profiler that collects time information for generated code.

Construction

H= Profiler(profilername)creates aProfilerobject and sets theNameproperty toprofilername.

Input Arguments

expand all

Profiler配置的名称,指定为字符串。

例子:

Data Types:char

Properties

expand all

Name ofProfiler目标支持的对象。金宝app默认值为''.

Data Types:char

Name of the file that contains the source code of the profiler function. The default is''.

The file specification must include a full path. The path can include tokens. If a path separator is included as part of the path, it must be valid for all supported host platforms.

Data Types:char

Name of the file that contains the declarations for the profiling function. The default is''.

The file must include a full path. The path can include tokens. If a path separator is included as part of the path, it must be valid for all supported host platforms.

Data Types:char

Name of the source code function that returns the profiling timer counter value. You must implement this function in a source file and specify the source file with propertySourceFile.

Data Types:char

Name of the data type of the return value of the profiling functionTimerReadFcn. The default is'uint32'.

Data Types:char

The resolution of the profiling timer in ticks per second. The default is1e9.

Data Types:double

The flag that denotes whether the profiling function counts up. The default is真的.

Data Types:logical

The flag that denotes whether the profiling function stores the ID of the core on which it executes. The default is真的.

Data Types:logical

The flag that denotes whether the profiling function prints the profiling data. The default is真的.

仅当生成的代码与文件系统上的硬件上运行,例如Linux,才可以打印数据®. If the generated code runs on hardware without a file system, data is collected in a source code buffer. The default is真的.

Data Types:logical

表示分析函数是否立即打印分析数据的标志。设置为真的, the profile data prints to the standard output as soon as it is collected. Otherwise, the profile data prints when the generated code terminates. The default is真的.

如果the profiling data prints instantly, the amount of data that can be collected is not limited by the profiling buffer size. However, since the data prints as it is collected, executing the print instruction may take some time. This can greatly affect the profiling timing data.

Data Types:logical

The name of the buffer in the generated code that holds the profiling data. The default is'profilingData'.

Data Types:char

生成的代码中的缓冲区大小,该代码容纳了分析数据。默认值为400.

一旦缓冲区完整,分析数据的收集就会停止。

Data Types:double

The name of the MATLAB function that retrieves the profiling data from a file or a buffer on hardware and copies the data to the MATLAB host computer. The default is''.

检索的来源取决于printdataproperty. If set to真的,该函数从文件中检索Profiler数据。如果false, the function retrieves the profiler data from the profiling buffer in the generated code running on the hardware.

Data Types:char
