Function Documentation

void GenerateTilingCode ( )

Generate code from the user model

Once the model has been fully populated calling this function will produce the C code wrapping each user kernel

void SetConstDir ( char * DirName )

Provides a folder name where to find constant files passed to ConstInfo()

Parameters

DirName A valid directory name

void SetGeneratedFilesNames	(	char *	CallTemplatesName,
		char *	CallTemplatesNameHeader
	)

Defines files's names for code generation output

These 2 names are having as default values: GenKernels.c, GenKernels.h

Parameters

CallTemplatesName	A .c file for user kernels C generated code
CallTemplatesNameHeader	A .h file to export user kernels C generated code

void SetInlineMode ( InlineModeT Mode )

Control code generation inline strategy

User kernels can be either always inlined, never inlined or inlined only if there is a single instance of a given user kernel

Parameters

Mode	Inline mode

void SetKernelOpts	(	KernelOptimizationT	On,
		KernelOptimizationT	Off
	)

Control user kernel optimizations

Previous optimization settings is changed based on On and Off parameters. Initial value is On for all optimizations.

Parameters

On	Optimizations to be turned ON
Off	Optimizations to be turned OFF

void SetL1MemorySize ( unsigned int Size )

Set the maximum amount in shared L1 memory that the AutoTiler can use

Parameters

Size	Maximum size in byte

void SetMemoryBaseNames	(	char *	L1SymbName,
		char *	L2SymbName,
		char *	L3SymbName
	)

Defines C symbol names used for user kernel's code generation

Default names are L1_Memory, L2_Memory, L3_Memory

Parameters

L1SymbName	C var name, pointer or array, for AutoTiler dynamic needs in cluster shared L1 memory
L2SymbName	C var name, pointer or array, for AutoTiler dynamic needs in L2 memory
L3SymbName	C var name, pointer or array, for AutoTiler dynamic needs in L3 memory (PreferedExecLoc)

void SetMemoryDeviceInfos	(	int	Count,
			...
	)

Configure memory devices, A list of count items where each item is a tuple of 5 elements Space AT_MemLocation_T Which memory space AvailableMemory int available memory to be used on this device MemmoryBaseName char * a legal C var name to be used as a base in this memory device ConstFileName char * a file name to be used if loading constant in this device is needed, flash device only ExtManaged int 0 if device configuration code should be generated, != 0 if managed externally

Parameters

Count Number of Items

void SetMemorySizes	(	unsigned int	L1Size,
		unsigned int	L2Size,
		unsigned int	L3Size
	)

Set the maximum amount in shared L1 memory, L2 internal memory and L3 external RAM that the AutoTiler can use

Parameters

L1Size	Maximum L1 size in byte
L2Size	Maximum L2 size in byte
L3Size	Maximum L3 size in byte

void SetStyle ( int Old )

Set user kernel style modelization mode. If Old=1 uses Kernel Arg property to express Ker Arg iter space, If Old=0 use KerArgSpace() extra argument instead.

Parameters

Old	Style mode, 0: New style, != 0 Old style

void SetSymbolDynamics ( )

Set variables used for AutoTiler dynamic needs in cluster shared L1 memory and in L2 memory to be dynamic, e.g pointers, instead of arrays

void SetSymbolNames	(	char *	L1SymbName,
		char *	L2SymbName
	)

Defines C symbol names used for user kernel's code generation

Default names are L1_Memory, L2_Memory

Parameters

L1SymbName	C var name, pointer or array, for AutoTiler dynamic needs in cluster shared L1 memory
L2SymbName	C var name, pointer or array, for AutoTiler dynamic needs in L2 memory

void SetUsedFilesNames	(	char *	StdTypedefsName,
		unsigned int	LibKernelFileCount,
			...
	)

Provides header file for basic kernels standard data type and a list of basic kernels header files

Parameters

StdTypedefsName	File names where standard typedefs used by basic kernels are declared
LibKernelFileCount	Number of header files for basic kernels to be imported into the current model, list of strings follows

int TilerParseOptions	(	int	argc,
		char **	argv
	)

Parses AutoTiler options and performs initialization

This function takes care of AutoTiler arguments parsing and of initialization.

Any user model should start with a call to it. it will return 0 if arguments are ok and if the initialization is sucessfull

Parameters

argc	Number of arguments
argv	A string for each argument
