lxvb16x

Load VSX Vector Byte*16 Indexed

lxvb16x XT,RA,RB

Loads a vector of 16 byte elements from memory into a VSX register.

Details

Loads a 128-bit vector containing 16 byte elements from memory into a VSX register. The effective address is computed as RA|0 + RB. No status fields are modified by this instruction.

Pseudocode Operation

EA ← (RA=0 ? 0 : GPR[RA]) + GPR[RB]
VSR[XT] ← MEM(EA, 16)

Programming Note

Exhibits identical behavior in Big-Endian mode.
