Member Function Documentation

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

inline

void SCI::sci_nco::destroy ( )

inlinevirtual

destroy SCI object

Reimplemented from SCI::sci_base.

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

virtual

execute command for an instance of NCO
Supported commands:
none

Parameters

[in] command - to be executed

Reimplemented from SCI::sci_base.

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

virtual

create new sci_var object and assign a its value to fixed point NCO parameter

Supported parameters:
SCI_TYPE,    sci_var [int] 

SCI_PARAM_N, sci_var [int] number of bits in fixed point fractional format Q1.N 

SCI_ACC,     sci_var [double] phase accumulator state in double fractional format

SCI_OUTPUT,  sci_var [vec] initial output value y0 = [cy|ph]

Parameters

[in] param - parameter to get

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

Reimplemented from SCI::sci_base.

sci_var * SCI::sci_nco::proc	(	sci_var *	p_v_ce,
		sci_var *	p_v_x
	)

virtual

return NCO output [y]=[cy|ph] in newly created sci_var [mat]
for active [ce] ticks, fractional phase accumulator sums fractional frequency control words in [x]

Parameters

[in]	p_v_ce	- pointer to ce - sci_var [bvec]
[in]	p_v_x	- pointer to x - sci_var [vec]

Returns: - pointer to y - created sci_var [mat]=[cy|ph]

Reimplemented from SCI::sci_base.

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

virtual

set parameters of a fixed point NCO - numerically controlled oscillator

Supported parameters:
SCI_PARAM_N, sci_var [int]  number of bits in fixed point fractional format Q1.N

SCI_ACC,     sci_var [double] phase accumulator state in double fractional format

SCI_OUTPUT,  sci_var [vec] initial output value y0 = [cy|ph]

Parameters

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

Reimplemented from SCI::sci_base.
