Shift Word Right Logical |
Shift Word Right Logical
To execute a logical right-shift of a word by a fixed number of bits.
GPR[rd] = GPR[rt] >> sa (logical)
The contents of the low-order 32-bit word of GPR rt are shifted right, inserting zeros into the emptied bits. The word result is sign-extended and placed in GPR rd. The bit-shift amount is specified by sa.
On 64-bit processors, if GPR rt does not contain a sign-extended 32-bit value (bits 63..31 equal), then the result of the operation is UNPREDICTABLE.
if NotWordValue(GPR[rt]) then UNPREDICTABLE endif s = sa temp = 0s || GPR[rt]31..s GPR[rd] = sign_extend(temp)
