Drag and Drop the name of the components on the right side that belongs to the CPU (Central
Processing Unit) on the left.

Answer:

Explanation:

The Central Processing Unit (CPU) or the processor is the portion of a computer system that carries
out the instructions of a computer program. It is a multifunctional integrated circuit that is essential
for a computer system. It is the primary element carrying out the computer’s functions. CPU is made
up of several parts that work together to carry out the instructions and actions. The CPU has
following components:

ALU: An arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations.
It is a fundamental building block of the central processing unit (CPU) of a computer, and even the
simplest microprocessors contain one for purposes such as maintaining timers. The processors found
inside modern CPUs and graphics processing units (GPUs) accommodate very powerful and very
complex ALUs, a single component may contain a number of ALUs.

FPU: FPU stands for floating-point unit. It is a part of a computer system that specially designed to
carry out operations on floating point numbers. It performs some typical operations such as
addition, subtraction, multiplication, division, and square root. Some systems (particularly older,
microcode-based architectures) can also perform various transcendental functions such as
exponential, logarithms, or trigonometric calculations. It handles floating point operations for the
ALU and CU.
MMU: MMU stands for memory management unit. It is also known as paged memory management
unit (PMMU), which is a computer hardware component responsible for handling accesses to
memory requested by the CPU. It handles addressing and cataloging of where data is stored in
system memory. Its functions include translation of virtual addresses to physical addresses (i.e.,
virtual memory management), memory protection, cache control, bus arbitration, and, in simpler
computer architectures (especially 8-bit systems), paging.
Control Unit: A control unit is a central part of a system that controls its operation. This unit redirects
the functions of the CPU. It tells the other parts of the CPU how to operate, what data to use, and
where to put results.
BIU: BIU stands for Bus Interface Unit. It supervises the transfer of data over the bus system
between the other components of the computer and the CPU. It also serves as the interface point
for the CPU and its external bus. It also handles the data transfer out of the control unit. BIU
provides various functions, including generation of the memory and I/O addresses for the transfer of
data.
PFU: PFU stands for prefetch unit. It preloads the instruction registers of the CPU with instruction
from memory whenever BIU is idle. PFU fetches instructions in advance and forwards PC relative
branch instructions. It detects thumb 32-bit instructions, presents these as a single instruction word
and performs vector loads. It does not analyze instructions, so on an occasion it will bring in an
unnecessary instruction.
PIO stands for programmed I/O, and it is a legacy data transfer protocol and I/O standard used by
many older disk drives that uses the CPU to execute instructions that move data form the disk drive
to RAM or the CPU.
LBA is a data addressing method and it simply lists a single logical location for each file. LBA is used
on SCSI and EIDE drives.
