A scalable register file architecture for dynamically scheduled processors
Steven Wallace, Nader Bagherzadeh · 2002
A major obstacle in designing dynamically scheduled processors is the size and port requirement of the register file. By using a multiple banked register file and performing dynamic result renaming, a scalable register file architecture can be implemented without performance degradation. In addition, a new hybrid register renaming technique to efficiently map the logical to physical registers and reduce the branch misprediction penalty is introduced. The performance was simulated using the SPEC95 benchmark suite.
