324 Energy-Aware Memory Management for EMSs
Please note that a modification of cost models would be needed for more
precise evaluation including clock and power gating schemes, dynamic voltage
and frequency scaling, etc. because the currently used models lack complexity.
They do, however, suffice for illustrative purposes. Equation 10.9 also means
each instruction consumes the same amount of energy per activation in all
PE implementation patterns that include the instruction. For a more precise
evaluation, the definition of E
D
should be modified when more precise data
are available given that each instruction consumes different energy amounts
for each implementation ...
