• Getting Started with Application Development

Changes to the Stack Size Parameter

The Real-Time Workshop®product (RTW ) has changed the way it performs stack analysis and control. For more information, see “Improved Stack Analysis and Control”in the RTW release notes.

In Embedded IDE Link models, when you set the System target file parameter on the Real-Time Workshop pane to

idelink_grt.tlc, the software sets the Maximum stack size pa ra m eter on

the Optimization pane to In that case, the Maximum stack size parameter compares the value of (System stack size/2) with 200,000 bytes and uses the smaller of the two values.

Inherit from target and makes it non-editable.

Avoiding Linker Errors Related to Stack Size

If RTW estimates the stack size is large enough, it redefines global variables and buffers from model_output and model_step functions as local variables. This optimization typically increases execution speed, and migh t also increase thesizeofthegeneratedcode. Ifthe generated code does not fit in the

5.0.5). Installing Update 5 significantly improves the performance of code you generate for embedded applications on Blackfin.

Support for Free-running ARM with Green Hills MULTI

Added support for free-running ARM processors with the Green Hills MULTI IDE.

Support for Green Hills MULTI 5.0.5 and 5.1.2

Added support for Green Hills MULTI 5.0.5 and 5.1.2.

Improved Handling of Asynchronous Hardware Interrupts for Blackfin Processors

For Analog Devices VisualDSP++ and Green Hills MULTI, Embedded IDE Link has changed the Blackfin base rate interrupt scheme to reduce latency for asynchronous hardware interrupts of various priorities.

In previous releases, the core timer generated a high-priority base rate interrupt (higher than any of the peripheral interrupts) and it’s interrupt service routine (ISR) executed the rtOneStep() function directly. As a consequence, any peripheral interrupts had to wait until the completion of the core timer ISR before they could execute.

Embedded IDE Link™ Release Notes

In 9b, instead of executing the rtOneStep() function, the high priority core timer interrupt raises a low priority software interrupt and exits. The low priority software interrupt, in turn, executes rtOneStep(). Because the priority of the software interrupt is lower than the priorities of any of the peripheral interrupts, the peripheral interrupts are now able to preempt the execution of rtOneStep() and thus get serviced with a smaller latency.

Removed "Inline run-time library functions" From Configuration Parameters

Removed the Inline run-time library functions parameter from the Configuration Parameters dialog box under

Embedded IDE Link.

Embedded IDE Link Build Directory and Target Preferences

You must use a clean build directory and the latest values for the target preference fields when setting up your installation.

Real Time Workshop >

Compatibility Considerations

To avoid problems when upgrading from a previous version, use either a new build directory, or clean up your existing build directory that you use to build models with the Embedded IDE Link product.

A previous installation of the Embedded IDE Link product could cause a compatibility issue if the target preferences are not reset. To avoid problems, click Reset to Default in the Embedded IDE Link Targ et Preferences dialog box before setting up your installation.

Note Resetting your target preferences overwrites any previously saved entries for the current MATLAB release.
