Float

Overview

Float vector comparison.

Performs the comparison between lanes and return the result of the comparison as a bit in the return word.

Function Documentation

unsigned int fpge	(	v8float	acc,
		v16float	xbuf,
		int	xstart,
		unsigned int	xoffs
	)

Greater-equal-operator of real single precision floating point vectors.

for (i = 0 ; i < 8 ; i++)
  ret[i] = acc[i] >= xbuf[xstart + xoffs[i]]

Returns

Scalar integer with one comparison result per bit.

Parameters

acc	Incoming accumulation vector.
xbuf	Input buffer. Small buffer variant.
xstart	Starting offset for all lanes of X.
xoffs	4 bits per lane: Additional lane-dependent offset for X.

Returns

Scalar integer with one comparison result per bit.

Parameters
