題目在第一頁,1.4題
我想問的是,"In technology A, the static power consumption takes about 10% of
the total power while in technology B, the static power takes about 25% of the
total power.Assume a CPU runs at frequency of 2GHz with supply voltage Vdd=1.5
volts in technology A and consumes a total power of 20 watt."
這句話的意思是technology A消耗了total power的20watt嗎?
如果是這樣的話,式子是不是應該為:PswA = (a*C*(1.5)^2*2GHz)*10% = 20watt
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
全部的power消耗10%為20watt
然後再去算PswB?
但手邊解答是寫 PswA = a*C*(1.5)^2*2GHz = 0.9*toaol power = 0.9*20,然後在去算
PswB。
是我誤會題意嗎? 懇請各位指點 謝謝
