Function Documentation

void DSPF_sp_mat_submat_copy	(	float *	x,
		int	rows,
		int	cols,
		int	st,
		int	n,
		float *restrict	y,
		int	dir
	)

If dir = 0, this function copies n rows starting from st row of matrix x to form matrix y; If dir != 0, this function copies n rows of y to matrix x; The values stored in x and y is single-precision floating values.

Parameters:

	x	= Pointer to r1 by c1 input matrix.
	rows	= Number of rows in x.
	cols	= Number of columns in x.
	st	= start index of rows in x to be copied.
	n	= Number of rows to be copied.
	y	= Pointer to the output matrix.
	dir	= data flow direction.

Algorithm:

DSPF_sp_mat_submat_copy_cn.c is the natural C equivalent of the optimized intrinsic C code withoutrestrictions. Note that the intrinsic C code is optimized and restrictions may apply.

Assumptions:

The arrays x and y are stored in distinct arrays. In-place processing is not allowed.
Rows, cols, st and n are assumed to be even.
x and y are aligned on double-word boundaries.

Implementation Notes:

Interruptibility : The code is interruptible.
Endian support : supports both Little and Big endian modes.
