andi.
AND Immediate
andi.
AND Immediate
(RA) ← (RS) ∧ (
16
0 || IM)
The IM field is extended to 32 bits by concatenating 16 0-bits on its left. The contents of register RS is
ANDed with the extended IM field; the result is placed into register RA.
Registers Altered
•RA
• CR[CR0]
LT, GT, EQ, SO
Programming Note
The andi. instruction can test whether any of the 16 least-significant bits in a GPR are 1-bits.
andi. is one of three instructions that implicitly update CR[CR0] without having an Rc field. The other
instructions are addic. and andis..
Architecture Note
This instruction is part of the PowerPC User Instruction Set Architecture.
