ystart	int	Starting position offset applied to all lanes for input from Y buffer.
xyconj	bool	Selector for conjugation in X and Y buffers
zbuff	v8cint16	Input buffer of 8 elements of type cint16
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
zconj	bool	Selector for conjugation in Z buffer

Note

• The previous pseudocode is just a simplified representation of how the operation works, when computed internally it will be done using pre-adding
• 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.
