Parameters

Input/Output	Type	Comments
return	v4cacc48	Returned accumulation vector (4 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 the x buffer. LSB apply to first lane
xstep	unsigned int	Step between each column for selection in the xbuffer.
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
zstep	int	Step between each column for selection in the zbuffer.
