xstartStarting position offset applied to all lanes of input from X buffer.
xoffsets4b offset for each lane, applied to both x and y buffers. LSB apply to first lane
xstepStep between each column for selection in the x and y buffers. Ystep is symmetric to xstep (ystep advances by -xstep).
ystartStarting position offset applied to all lanes for input from Y buffer.
xyconjSelector for conjugation in X and Y buffers
uct_colSelect 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_shiftUpshift value to the four upshifted lanes
zbuffInput buffer of 8 elements of type int32
zstartStarting 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.
zoffsets4b offset for each lane, applied to input from Z buffer. LSB apply to first lane
zstepStep between each column for selection in the zbuffer.

  • Parameter 'zstart' must be a compile time constant.
