The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
The arithmetic logic unit(ALU) decides the performance of the Central Processing Unit(CPU), while the adder decides that of the ALU.
It is given that the detailed design of the integer execution unit, include ALU, multiplier, barrel shifter and register files.
Arithmetic unit: arithmetic unit is a data processing unit that consists of arithmetic logic unit (ALU), accumulator, data buffer, ect.
ALU從輸入寄存器裝入數據，接着執行，然後將結果存儲在輸出寄存器。
重點討論了其中的整數執行部件的設計，包括ALU、乘法器、桶式移位器、寄存器堆等重要執行部件。
It has been found that the major limitations of typical 8-bit MCU are the ALU structure based on accumulator and the CISC architecture adopted in MCS-51 design.
分析發現，在傳統八位微控制器設計中，基於累加器的ALU結構及CISC指令體系及系統構架是影響其整體*能的主要原因。
