Register Renaming refers to eliminating output and anti dependencies by automatically allocating new registers to values, when such a dependency has been detected.

Example for output dependency;

MUL        R4,R3,R1       R4 <= R3 * R1

----------------------------------------------------

ADD       R4,R2,R5        R4 <= R2 + R5

(ADD      R6,R2,R5        R6 <= R2 + R5)
