注意这个算法首先执行一个乘法，然后又执行一个除法(移位)。
Note that the algorithm performs a multiply first and a divide (shift) later.
重点讨论了其中的整数执行部件的设计，包括ALU、乘法器、桶式移位器、寄存器堆等重要执行部件。
It is given that the detailed design of the integer execution unit, include ALU, multiplier, barrel shifter and register files.
与传统的移位乘法器相比，它将乘法器速度提高一倍。
Compared with the traditional serial multiplier, it can obtain twice speed-up.
