In recent years , ORGANIZATION@1 techniques have been used to provide performance improvements in spite of the growing disparity between processor operating frequencies and memory access times -LRB- early ORGANIZATION@1 designs such as the ORGANIZATION@2 NUMBER@1 used ORGANIZATION@1 techniques to overcome the limitations imposed by a relatively small register file -RRB- .

In recent years , ORGANIZATION@1 techniques have been used for performance improvements in conditions where the difference between processor operating frequencies and memory access times is large .
