移位（bit shifting）
移位只对整数运算起作用。通过移位进行2的整数次幂的乘除法要比直接进行乘法运算快很多（当然比除法运算更快），这是一个基本常识。 More >

来自CCS的help:
The compiler analyzes data flow to avoid memory accesses whenever possible.

A variable qualified with a volatile keyword is allocated to an uninitialized section (as opposed to a register). The compiler does not optimize out any references to volatile variables. More >
