消耗低，一般低于30%的额外运行时间和50%的代码体积增长。

Very low overhead; typically less than 30% longer runtime and 50% extra code size.

为了让芯片运行的更快，晶体管必须缩小体积，但是更小的晶体管不消耗更少的能量的话就会过热。

For a chip to speed up, its transistors need to be shrunk, but smaller transistors must consume less power or they overheat.

但是，这些液晶显示器必须要背光照明才能正常工作，这就带来了更大的电池消耗，以及限制了它们体积的进一步小型化。

But these LCDs must be backlit to work properly-which can be a big battery drain and limits how small the gadgets can be made.
