Although large caches can significantly improve performance they have the potential to increase power consumption As feature sizes shrink the dominant component of this power loss will be leakage However during a fixed period of time the activ ity i caches and data caches are always identical in size or differ by a factor of 2X, but no more. The primary caches range from 8 KB to 128 KB with SA ranging from direct mapped to 8-way. Small instruct Optimization. Techniques. . Presented by . Preethi Rajaram.
