Vector Shift Right Variable

Result value

Let v be a 17-byte vector formed from a zero byte in element 0 and the elements of a in bytes [1:16]. Then each byte element i of r is determined as follows. The start bit sb is obtained from bits 5:7 of byte element i of b. Then the contents of bits (8 – sb):(15 – sb) of the halfword in byte elements i:i+1 of v are placed into byte element i of r.

Endian considerations

All bit and byte element numbers are specified in big-endian order. This intrinsic is not endian-neutral.
