modification of interrupt block

I think that the best way will be to modify an exsisting interrupt block...


Creating a Customized Asynchronous Library


This section describes how to implement asynchronous blocks for use with your target RTOS, using the Async Interrupt and Task Synchronization blocks as a starting point. (Rate Transition blocks are target-independent, so you do not need to develop customized rate transition blocks.)

You can customize the asynchronous library blocks by modifying the block implementation. These files are

The block's underlying S-function MEX-file

The TLC files that control code generation of the block

In addition, you need to modify the block masks to remove VxWorks-specific references and to incorporate parameters required by your target RTOS.

Custom block implementation is an advanced topic, requiring familiarity with the Simulink MEX S-function format and API, and with the Target Language Compiler (TLC). These topics are covered in the following documents:

The Overview of S-Functions in the Simulink S-Functions documentation describes MEX S-functions and the S-function API in general.

The Target Language Compiler documentation and Writing S-Functions for Real-Time Workshop describe how to create a TLC block implementation for use in code generation.

The sections below discuss the C/C++ and TLC implementations of the asynchronous library blocks, including required SimStruct macros and functions in the TLC asynchronous support library (asynclib.tlc)
