Member Function Documentation

sci_lfsr* SCI::sci_lfsr::create ( int sci_type )

inline

void SCI::sci_lfsr::destroy ( )

inlinevirtual

destroy SCI object

Reimplemented from SCI::sci_base.

void SCI::sci_lfsr::exec ( int command )

virtual

execute command for an instance of a LFSR

Supported commands:
SCI_RESET

Parameters

[in] command - to be executed

Reimplemented from SCI::sci_base.

sci_var * SCI::sci_lfsr::gen ( sci_var * p_v_ce )

virtual

for active [ce] ticks, assign newly created symbol [bvec] to output row

Parameters

[in] p_v_ce - pointer to ce - sci_var [bvec]

Returns: - pointer to y - new sci_var [bmat]

Reimplemented from SCI::sci_base.

sci_var * SCI::sci_lfsr::get ( int param )

virtual

create new sci_var object and assign its value to LFSR parameter

Supported parameters:
SCI_TYPE,  sci_var [int] 

SCI_SYMBOL_SIZE,  sci_var [int] 

SCI_LENGTH,  sci_var [int] 

SCI_POLY,  sci_var [bvec] 

SCI_STATE, sci_var [bvec] 

SCI_RESET_STATE, sci_var [bvec] 

SCI_OUTPUT, sci_var [bvec] 

SCI_REVERSE_FLAG sci_var [bool]

Parameters

[in] param - parameter to get

Returns: - pointer to created sci_var, actual object type depends on input parameter

Reimplemented from SCI::sci_base.

void SCI::sci_lfsr::set	(	int	param,
		sci_var *	p_v
	)

virtual

set parameters of a LFSR

Supported parameters:
SCI_POLY,        sci_var [bvec]

SCI_STATE,       sci_var [bvec]

SCI_RESET_STATE, sci_var [bvec]

SCI_OUTPUT,      sci_var [bvec]

SCI_SYMBOL_SIZE, sci_var [int]

SCI_PRBS,        sci_var [int]

SCI_REVERSE_FLAG sci_var [bool]

Note: SET SCI_POLY or SCI_PRBS and SCI_SYMBOL_SIZE are necessary configuration

Parameters

[in]	param	- parameter to set
[in]	p_v	- pointer to sci_var object with value of the parameter

Reimplemented from SCI::sci_base.
