Instead of printing the output at the end of the profile run, you can save the Not recurse, these two values are the same, and only the single figure is The second value is the number of primitive callsĪnd the former is the total number of calls. When there are two numbers in the first column (for example 3/1), it means Provides the respective data of each function Is the quotient of cumtime divided by primitive calls filename:lineno(function) This figure is accurate even for recursive functions. Is the cumulative time spent in this and all subfunctions (from invocation Is the quotient of tottime divided by ncalls cumtime ![]() The column headings include: ncallsįor the total time spent in the given function (and excluding time made in Next line: Ordered by: cumulative time, indicates that the text string in theįar right column was used to sort the output. Were primitive, meaning that the call was not induced via recursion. The first line indicates that 214 calls were monitored. Let us know how you got started with the coders by leaving a comment here.214 function calls ( 207 primitive calls ) in 0.002 seconds Ordered by : cumulative time ncalls tottime percall cumtime percall filename : lineno ( function ) 1 0.000 0.000 0.002 0.002 1 0.000 0.000 0.001 0.001 : 1 ( ) 1 0.000 0.000 0.001 0.001 _init_. This example is probably the simplest one possible, but I hope this gives you a good idea of how to get started. There are many of ways to customize the code generated by Embedded Coder. With this modification, the generated code integrates in the hand-written application, I can build the main program without errors. Generate code for the model, and you should get something which looks like this: Go to the Code Generation tab, and set the storage class to ImportedExtern (Note that the storage class and a lot more could also have been specified using a data object). Then we need to tell Embedded Coder that u and y are external variables, already defined outside of the generated code, in the hand-written code.įor that, right-click on the signal line and select Properties: To configure the look of the code, the first step is to name the input signal u and the output y. ![]() It is obvious that modifications are necessary to map the values of u and y in the hand-written code to the input and output of the generated code. ![]() We want our auto-generated code to access this variable, and use it to compute value of another global variable y to be used later in the code.įor this example, let's use the following simple model.īy default, if we generate code for this model we get something that looks like: In this simple main, at every second, the program reads data from a text file and stores it in a global variable u. To illustrate that, we will start with a simple hand-written program, and see how to configure a model so that the code generated from it integrates without modification. If you ask me what is the difference between Simulink Coder and Embedded Coder, I would tell you that Simulink Coder allows you to generate code from a Simulink model, and Embedded Coder allows you to configure how the code looks like. For readers who never used it, I hope this example will be as useful for you as it has been for me. This week, I want to share the example which helped me, a long time ago, to get started with Embedded Coder.
