Simple Float Vector Lane Selection
Shuffle: Shuffle selects from a single input acording to the start/offset computation.
- Note
- fpsel behaves as a "shuffle" intrinsic.

ret[i] = xbuf[xstart + xoffs[i]]
~~~~~~~~~~~~~~~~~~~
- Returns
- Result vector.
- Parameters
-
| xbuf | Input buffer. |
| xstart | Starting offset for all lanes of X. The start value refers to complex lanes (lane 0 corresponds to the first real and imaginary value). |
| xoffs | 4 x 4 bits: Additional lane-dependent offset for X. Highest (4th) bit in each lane must be 0. Range per lane : [0,7] The offsets are referring to complex lanes (lane 0 corresponds to the first real and imaginary value).
