Function Documentation

void DSPF_sp_dotp_cplx	(	const float *	x,
		const float *	y,
		int	nx,
		float *restrict	re,
		float *restrict	im
	)

This routine calculates the dot product of 2 single-precision complex float vectors. The even numbered locations hold the real parts of the complex numbers while the odd numbered locations contain the imaginary portions.

Parameters:

	x	Pointer to array holding the first floating-point vector
	y	Pointer to array holding the second floating-point vector
	nx	Number of values in the x and y vectors
	re	Pointer to the location storing the real part of the result
	im	Pointer to the location storing the imaginary part of the result

Algorithm:

DSPF_sp_dotp_cplx_cn.c is the natural C equivalent of the optimized linear assembly code without restrictions. Note that the linear assembly code is optimized and restrictions may apply.

Assumptions:

Loop counter must be multiple of 4 and > 0.
The x and y arrays must be double-word aligned.

Implementation Notes:

Interruptibility: The code is interruptible.
Endian Support: The code supports both big and little endian modes.
