Parameters

Input/Output	Type	Comments
return	v8cacc48	Returned accumulation vector (8 x cint48 lanes)
xbuff	v16cint16	Input buffer of 16 elements of type cint16
xstart	int	Starting position offset applied to all lanes of input from X buffer.
xoffsets	unsigned int	4b offset for each lane, applied to both x and y buffers. LSB apply to first lane
xstep	unsigned int	Step between each column for selection in the x and y buffers. Ystep is symmetric to xstep (ystep advances by -xstep).
ystart	int	Starting position offset applied to all lanes for input from Y buffer.
xyconj	bool	Selector for conjugation in X and Y buffers
uct_col	int	Select which column of data from the Y buffer to upshift for the lower half of the output accumulator. This must be a compile time constant.
uct_shift	int	Upshift value to the four upshifted lanes
zbuff	v16int16	Input buffer of 16 elements of type int16
zstart	int	Starting position offset applied to all lanes for input from Z buffer. This must be a compile time constant. Only the 4 LSB of the argument are used.
zoffsets	unsigned int	4b offset for each lane, applied to input from Z buffer. LSB apply to first lane
zstep	int	Step between each column for selection in the zbuffer.

• For more information on how data selection works from the buffers go here. The data buffer and coefficient buffer in this intrinsic use the general scheme.
• Parameter 'zstart' must be a compile time constant.
