Description
The central Processing Unit (CPU) is a large scale integrated battery, which is the computing Core
and Control Unit of a computer. Its function is mainly explain refers to computer today and dealing with
data in a computer software, the CPU mainly includes arithmetic unit (arithmetic logic operation unit,
ALU, Arthmetic logic Unit, Cache, and the Bus that connects them, Data, control, and state, together
with internal Memory and input/output (/0) devices, are called the three core components of electronic
computers. The CPU can be divided into 3 modules from the logic, which are the control unit, the
computing unit and the storage unit, which are connected by the internal bus of the CPU

The control unit is the command and control center of the whole CPU, consisting of the Regist
er IR(lnstruction Register), the instruction Decoder ID(nstruction Decoder) and the operation
controller OC(OperationControllerl), etc. It is very important to coordinate the whole comput
er to work in order. According to the user’s pre-programmed program, it takes out each instr
uction from the memory in turn, puts it in the instruction register IR, determines what operati
on should be carried out through instruction decoding (analysis), and then sends a microope
ration control signal to the corresponding component by operating the controller OC, accord
ing to the determined timing. The operation controller OC mainly includes the control logic of
beat pulse generator, control matrix, clock pulse generator, reset circuit and power off circuit.
