CPU模塊，全稱中央處理器模塊，是一種集成了CPU芯片和相關(guān)電路的組件，是計(jì)算機(jī)系統(tǒng)的核心部件。它的主要功能是執(zhí)行各種指令和進(jìn)行數(shù)據(jù)處理，通過(guò)時(shí)鐘信號(hào)驅(qū)動(dòng)，根據(jù)指令集和算法完成計(jì)算任務(wù)。
CPU模塊從邏輯上可以劃分成三個(gè)主要部分：
控制單元：IC697CPM924這是整個(gè)CPU的指揮控制中心，負(fù)責(zé)協(xié)調(diào)整個(gè)電腦有序工作。它根據(jù)用戶預(yù)先編好的程序，依次從存儲(chǔ)器中取出各條指令，放在指令寄存器中，通過(guò)指令譯碼確定應(yīng)該進(jìn)行什么操作，然后通過(guò)操作控制器，按確定的時(shí)序，向相應(yīng)的部件發(fā)出微操作控制信號(hào)。
運(yùn)算單元：這是運(yùn)算器的核心，可以執(zhí)行算術(shù)運(yùn)算(包括加減乘數(shù)等基本運(yùn)算及其附加運(yùn)算)和邏輯運(yùn)算(包括移位、邏輯測(cè)試或兩個(gè)值比較)。運(yùn)算單元接受控制單元的命令而進(jìn)行動(dòng)作，即運(yùn)算單元所進(jìn)行的全部操作都是由控制單元發(fā)出的控制信號(hào)來(lái)指揮的。
存儲(chǔ)單元：包括CPU片內(nèi)緩存和寄存器組，是CPU中暫時(shí)存放數(shù)據(jù)的地方，里面保存著那些等待處理的數(shù)據(jù)或已經(jīng)處理過(guò)的數(shù)據(jù)。CPU訪問(wèn)寄存器所用的時(shí)間要比訪問(wèn)內(nèi)存的時(shí)間短，因此采用寄存器可以減少CPU訪問(wèn)內(nèi)存的次數(shù)，從而提高CPU的工作速度。

CPU module, the full name of the central processor module, is a component that integrates the CPU chip and related circuits, and is the core component of the computer system. Its main function is to execute various instructions and data processing, driven by the clock signal, according to the instruction set and algorithm to complete the calculation task.
The CPU module can be logically divided into three main parts:
Control unit: IC697CPM924 This is the command and control center of the entire CPU, responsible for coordinating 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 a microoperation control signal to the corresponding component by operating the controller according to the determined timing.
Arithmetic unit: This is the core of the arithmetic unit and can perform arithmetic operations (including basic operations such as addition and subtraction multipliers and their additional operations) and logical operations (including shifts, logic tests, or comparisons between two values). The operation unit accepts the command of the control unit and acts, that is, all the operations carried out by the operation unit are commanded by the control signal issued by the control unit.
Storage unit: IC697CPM924 includes CPU on-chip cache and register group, which is the temporary storage of data in the CPU, storing the data waiting to be processed or the data that has been processed. The time used by the CPU to access the register is shorter than the time used to access the memory, so the use of registers can reduce the number of times the CPU accesses the memory, thereby improving the CPU speed.
