xstep unsigned int Step between each column for selection in the x and y buffers. Ystep is symmetric to xstep (ystep advances by -xstep).
ybuff v16cint16Right input buffer of 16 elements of type cint16
ystart int Starting position offset applied to all lanes for input from Y buffer.
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 v8cint16Input 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.
zoffsetsunsigned 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.
