RTW.CImplementation

Specify implementation function for a block replacement entry

Since R2024a

Description

Use RTW.CImplementation objects to specify implementation functions for a block replacement entry. You can specify implementation functions for the initialize, update, output, and terminate functions.

Creation

Syntax

implementation = RTW.CImplementation

Description

implementation = RTW.CImplementation creates an RTW.CImplementation object.

Properties

HeaderFile — Name of header file that declares implementation function

'' (default) | character vector | string scalar

Name of the header file that declares the implementation function, specified as a character vector or string scalar.

Example: 'ImplementationHeaderFile',''

HeaderPath — Path to implementation header file

'' (default) | character vector | string scalar

Full path to the implementation header file, specified as a character vector or string scalar.

Example: 'ImplementationHeaderPath',''

Name — Name of implementation function

'' (default) | character vector | string scalar

Name of the implementation function, specified as a character vector or string scalar.

Example: 'arm_fir_init'

SourceFile — Name of implementation source file

'' (default) | character vector | string scalar

Name of the implementation source file, specified as a character vector or string scalar.

Example: 'ImplementationSourceFile',''

SourcePath — Path to implementation source file

'' (default) | character vector | string scalar

Full path to the implementation source file, specified as a character vector or string scalar.

Example: 'ImplementationSourcePath',''

Object Functions

addArgument	Add argument to RTW.CImplementation object
setReturn	Add return argument to RTW.CImplementation object

Examples

Add Initialization Function to a Block Replacement Entry

Specify an implementation function to replace the initialize function of a Discrete FIR Filter block.

Create a block replacement entry for the Discrete FIR Filter block.

hLib = RTW.TflTable;

entry = RTW.TflBlockEntry;
entry.Key = 'DiscreteFir';
entry.Priority = 1;

Create the RTW.CImplementation object that represents the implementation function. Specify the name and header file for the function.

impl = RTW.CImplementation;
impl.Name = 'arm_fir_init';
impl.HeaderFile = 'arm_math.h';

Specify the arguments that implementation function takes.

arg = getTflArgFromString(hLib, 'u1', 'uint16');
addArgument(impl, arg);

Add the implementation function to the block replacement entry as the replacement initialization function.

addImplementation(entry, 'initialize', impl);
