The simulations show that 2L-MuRR improves the RRF capacity greatly,over 70%. By using 2L-MuRR,SMT can achieve the same high performance with fewer rename registers,effectively reducing the design pressure on the register file.

• 模拟实验表明；2L-MuRR显著提高了RRF的存储能力(70%25以上)；能以较少的重命名寄存器满足SMT高并行度的要求；有效缓解了寄存器文件的设计压力.
