Function Documentation

§ APULPF3_unitCircle()

int_fast16_t APULPF3_unitCircle	(	uint16_t	numPoints,
		uint16_t	constant,
		uint16_t	phase,
		bool	conjugate,
		APULPF3_ComplexVector *	result
	)

Generate points evenly distributed on a unit circle. The APU generates a unit circle as follow: exp(-j*2*pi*(k*M+phase)/1024 * (-1)^(conjugate))

k = 0:N-1
M = 10-bit constant
phase = 10-bit constant
conjugate = 0 or 1

Parameters

[in]	numPoints	the number of points to generate (k)
[in]	constant	a 10-bit constant (M)
[in]	phase	a constant in (k*M+phase)
[in]	conjugate	whether or not to conjugate the output
[out]	result	a pointer to a vector where the output will be placed

Note: See ti_drivers_APU_DataManagement for directions on efficient APU memory management.

Returns: A status code indicating whether the APU operation was a success.

Return values

APULPF3_STATUS_SUCCESS The call was successful.

§ APULPF3_HermLo()

int_fast16_t APULPF3_HermLo	(	APULPF3_ComplexTriangleMatrix *	mat,
		APULPF3_ComplexTriangleMatrix *	result
	)

converting Hermitian upper-triangular to lower-triangular

APU accelerator for converting converting Hermitian upper-triangular to lower-triangular. To save memory, APU stores only upper-triangular elements of Hermitian matrix in column-major order. This function converts this format to lower-triangular, column-major order Hermitian.
