Anti-symmetric multiply-negate intrinsic function with unit center-tap optimization with pre-sub from x input buffer using small X input buffer.
| xbuff | Input buffer of 32 elements of type int16 |
| xstart | Starting position offset applied to all lanes of input from X buffer. xstart is restricted to multiples of 2 as granularity for xbuff is 32-bit. |
| xoffsets | 4b offset for each lane, while each second lane is an offset to the lane before + 1, 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). xstep is restricted to multiples of 2 as granularity for xbuff is 32-bit. |
| xsquare | Select order of the mini-permute square (default=0x3210). LSB apply to first element |
| ystart | Starting position offset applied to all lanes for input from Y buffer. |
| ysquare | Select order of the mini-permute square (default=0x3210). LSB apply to first element |
| 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 16 elements of type int16 |
| 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. |
