New Target Configuration Parameter for Enabling Real-Time Workshop Compiler Optimization Level Control V5. 0 (R2007b) Real-Time Workshop Embedded Coder introduces a new target configuration parameter, CompOptLevelCompliant. This parameter indicates whether a target supports the new Real-Time Workshop configuration parameter Compiler Optimization Level. (Compiler Optimization Level controls the compiler optimization level for building generated code; for more information, see "Controlling Compiler Optimization Level and 77 Real-Time Workshop® Embedded CoderTM Release Notes Specifying Custom Optimization Settings" in the Real-Time Workshop documentation. ) When the CompOptLevelCompliant target configuration parameter is set to on, the Compiler Optimization Level parameter is displayed in the Real-Time Workshop pane of the Configuration Parameters dialog box for your model. If the CompOptLevelCompliant parameter is not set to on, the Compiler Optimization Level parameter does not appear. By default, the CompOptLevelCompliant parameter is set to off for custom targets and on for targets provided by Real-Time Workshop and Real-Time Workshop Embedded Coder. To make a target compliant, use the SelectCallback function to set CompOptLevelCompliant to on, and then modify the target makefile to honor the setting for Compiler Optimization Level, in the manner of the targets provided by Real-Time Workshop and Real-Time Workshop Embedded Coder. New Interactive Guided Introduction Demo An interactive demo of Real-Time Workshop Embedded Coder is available. This demo shows you how to apply MathWorks products to the basic steps that are common to most projects that design and implement a control algorithm. To view the demo: 1 In the MATLAB command window, enter the following command: >> rtwdemos The Real-Time Workshop Demos page is displayed. 2 Scroll down to Step-by-Step Code Generation Process under Guided Tutorials. Help displays the names of the modules that comprise the Step-by-Step Code Generation Process demo. To begin viewing the demo, click the name of the first module, Introduction, then proceed through subsequent modules in order, or jump directly to any that are of particular interest. 78 Version 5. 0 (R2007b) Real-Time Workshop® Embedded CoderTM Software New and Enhanced Demos The following demos have been added: Demo. . . rtwdemo_pcgd_intro Shows How You Can. . . Apply MathWorks products to the basic steps that are common to most projects that design and implement a control algorithm. For more information, see "New Interactive Guided Introduction Demo" on page 78. Use Target Function Libraries (TFLs) to replace operators and functions in generated code. With each example model included in this demo, a separate Target Function Library is provided to illustrate the creation of operator and function replacements using a MATLAB based API, and how to register the replacements with Simulink. rtwdemo_tfl_script The following demo has been enhanced to illustrate code traceability improvements in R2007b, including block-to-code highlighting and traceability report enhancements: · rtwdemo_hyperlinks 79 Real-Time Workshop® Embedded CoderTM Release Notes Version 4. 6. 1 (R2007a+) Real-Time Workshop Embedded Coder Software This table summarizes what's new in Version 4. 6. 1 (R2007a+): New Features and Changes No Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No 80 Version 4. 6 (R2007a) Real-Time Workshop® Embedded CoderTM Software Version 4. 6 (R2007a) Real-Time Workshop Embedded Coder Software This table summarizes what's new in Version 4. 6 (R2007a): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No New features and changes introduced in this version are · "Controlling Step Function Prototypes for Models" on page 81 · "New ModelStepFunctionPrototypeControlCompliant Target Configuration Parameter" on page 83 · "New ERT Target for Generating Host-Based Shared Libraries" on page 84 · "Enhanced Software-in-the-loop (SIL) Testing with New Portable Word Sizes Option" on page 86 · "New Code Style Options for Controlling Expression Optimizations in Generated Code" on page 87 · "Enhanced MISRA C Compliance" on page 88 · "New and Enhanced Demos" on page 88 Controlling Step Function Prototypes for Models In previous releases, there were only limited ways to control the function prototype of an ERT-based model's generated model_step function. The default model_step function prototype resembles the following: void model_step(void); If you generate reusable, reentrant code for an ERT-based model, the model's root-level inputs and outputs, block states, parameters, and external outputs are passed in to model_step using a function prototype that resembles the following: 81 Real-Time Workshop® Embedded CoderTM Release Notes void model_step(inport_args, outport_args, BlockIO_arg, DWork_arg, RT_model_arg); This release adds more flexible user control over the model_step function prototype that is generated for ERT-based Simulink models. From the Interface pane of the Configuration Parameters dialog box, you can click a new Configure Functions button that launches a Model Step Functions dialog box. Based on the Function specification value you select for your model_step function (supported values include Default model-step function and Model specific C prototype), you can preview and modify the function prototype. Here is a sample dialog box: Once you validate and apply your changes, you can generate code based on your function prototype modifications. 82 Version 4. 6 (R2007a) Real-Time Workshop® Embedded CoderTM Software Alternatively, you can use function prototype control functions to programmatically control model_step function prototypes. For more information, see "Configuring Model Function Prototypes Programmatically" in the Real-Time Workshop Embedded Coder documentation. You can also control step function prototypes for nonvirtual subsystems, if you generate subsystem code using right-click build. To launch the Model Step Functions for subsystem dialog box, use the function RTW. configSubsystemBuild: RTW. configSubsystemBuild('model/subsystem') RTW. configSubsystemBuild(gcb) Right-click building the subsystem will generate the step function according to the customizations you make. For more information about controlling model_step function prototypes, see the sections "Configuring the Target Hardware Environment" and "Controlling Generation of Function Prototypes" in the Real-Time Workshop Embedded Coder documentation.
