As was expected due to the results previously shown,
Way-Prediction achieves the best results, being able to reduce
energy consumption up to 82.1%. Meanwhile, the PS-Cache
obtains the worst results, since it is also the scheme that
accesses more ways. Analogously, Figure 4(b) depicts the
same results, but for the L2 cache. The Tag Filter Cache is
able to reduce consumption by 51.8%, 72.2%, 81.1% and
85.9% for a tag filter with one, two, three and four bits
respectively.
