IC697CPU771 CPU模塊從邏輯上可以劃分成三個主要模塊：
控制單元：IC697CPU771 是整個CPU的指揮控制中心，對協(xié)調(diào)整個電腦有序工作極為重要。它根據(jù)用戶預(yù)先編好的程序，依次從存儲器中取出各條指令，放在指令寄存器中，通過指令譯碼確定應(yīng)該進行什么操作，然后向相應(yīng)的部件發(fā)出微操作控制信號。
運算單元：是運算器的核心，可以執(zhí)行算術(shù)運算（包括加減乘除等基本運算及其附加運算）和邏輯運算（包括移位、邏輯測試或兩個值比較）。
存儲單元：包括CPU片內(nèi)緩存和寄存器組，是CPU中暫時存放數(shù)據(jù)的地方，保存著等待處理的數(shù)據(jù)或已經(jīng)處理過的數(shù)據(jù)。IC697CPU771CPU訪問寄存器所用的時間要比訪問內(nèi)存的時間短，因此采用寄存器可以提高CPU的工作速度。

The IC697CPU771 CPU module can be logically divided into three main modules:
Control unit: IC697CPU771 is the command and control center of the entire CPU, which is extremely important to coordinate the orderly work of the entire computer. According to the user's pre-programmed program, it takes out each instruction from the memory in turn, puts it in the instruction register, determines what operation should be carried out through the instruction decoding, and then sends out the microoperation control signal to the corresponding component.
Arithmetic unit: It is the core of the arithmetic unit and can perform arithmetic operations (including basic operations such as addition, subtraction, multiplication and division and its additional operations) and logical operations (including shifting, logic testing, or comparing two values).
Storage unit: including the CPU chip cache and register group, is a temporary storage of data in the CPU, saving the data waiting for processing or has been processed data. IC697CPU771 The CPU uses less time to access registers than to access memory, so the use of registers can improve the CPU speed.
