Doubleword Rotate Right |
Doubleword Rotate Right
To execute a logical right-rotate of a doubleword by a fixed amount-0 to 31 bits.
GPR[rd] = GPR[rt] <= (right) sa
The doubleword contents of GPR rt are rotated right; the result is placed in GPR rd. The bit-rotate amount in the range 0 to 31 is specified by sa.
s = 0 || sa GPR[rd] = GPR[rt]s-1..0 || GPR[rt]63..s
