Function Documentation

void DSPF_sp_mat_mul_cplx	(	const float *	x1,
		int	r1,
		int	c1,
		const float *	x2,
		int	c2,
		float *restrict	y
	)

This function computes the expression “y = x1*x2" for the matrices x1 and x2. The columnar dimension of x1 must match the row dimension of x2. The resulting matrix has the same number of rows as x1 and the same number of columns as x2. Each element of Matrices are assumed to be complex numbers with real values are stored in even word positions and imaginary values in odd positions.

Parameters:

	x1[2*r1*c1]	Input matrix containing r1*c1 complex floating-point numbers
	r1	Number of rows in matrix x1.
	c1	Number of columns in matrix x1. Also number of rows in matrix x2.
	x2[2*c1*c2]	Input matrix containing c1*c2 complex floating-point
	c2	Number of columns in matrix x2.
	y[2*r1*c2]	Output matrix of c1*c2 complex floating-point numbers

Algorithm:

DSPF_sp_mat_mul_cplx.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:

r1, c1, c2 are multiple of 2.
x1, x2 and y should be double-word aligned.

Implementation Notes:

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