◆ fpmul_cn() [5/7]

v4cfloat fpmul_cn	(	v4cfloat	xbuf,

	)

Multiply and negate for single precision complex conjugate times complex floating point vectors.

for (i = 0; i < 4; i++)

ret[i] = - (conj(xbuf[xstart + xoffs[i]]) * zbuf[zstart + zoffs[i]])

Note: This is a two-cycle intrinsic which will result in two microcode instructions to be scheduled. The same behavior can be achieved by calling the fully configurable multiply-accumulate intrinsic twice in order to add the two terms of the complex multiplication.

Returns: Result vector.

Parameters

xbuf	First multiplication input buffer.
xstart	Starting offset for all lanes of X. The start value refers to complex lanes (lane 0 corresponds to the first real and imaginary value).
xoffs	4 x 4 bits: Additional lane-dependent offset for X. Highest (4th) bit in each lane must be 0. Range per lane : [0,7]

The offsets are referring to complex lanes (lane 0 corresponds to the first real and imaginary value).

Note: When xoffs is a runtime parameter, it might be more efficient to use fpmac_conf and calculate the offsets manually.

Parameters

zbuf	Second multiplication input buffer.
zstart	Starting offset for all lanes of Z. This must be a compile time constant. The start value refers to complex lanes (lane 0 corresponds to the first real and imaginary value).
