Parameters

xbuff	Input buffer of 32 elements of type cint16
xstart	Starting position offset applied to all lanes of input from X buffer.
xoffsets	4b offset for each lane, applied to both x and y buffers. LSB apply to first lane
xstep	Step between each column for selection in the x and y buffers. Ystep is symmetric to xstep (ystep advances by -xstep).
ystart	Starting position offset applied to all lanes for input from Y buffer.
uct_col	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	Upshift value to the four upshifted lanes
zbuff	Input buffer of 8 elements of type int32
zstart	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	4b offset for each lane, applied to input from Z buffer. LSB apply to first lane
zstep	Step between each column for selection in the zbuffer.
