The CPU is the "brain" of the computer, responsible for executing instructions and processing data.

The ALU performs arithmetic and logical operations within the CPU.

The control unit manages and coordinates the execution of instructions.

The program counter (PC) keeps track of the memory address of the next

The CPU fetches, decodes, and executes instructions from memory

The instruction set is the collection of commands a CPU can execute.

Data transfer instructions move data between registers, memory, and I/O

Instructions consist of an opcode (operation code) and operands (data or addresses).

The ADD instruction performs addition on data stored in registers or memory.

The opcode specifies the operation the CPU must perform.

The accumulator stores results of arithmetic and logical operations.

Overclocking boosts performance by running the CPU at a higher frequency than specified.

Hyper-threading allows a single physical core to appear as two logical cores for simultaneous task execution.

RISC simplifies instruction execution, allowing for faster and more efficient processing.

Intel x86 processors use the Complex Instruction Set Computing (CIS  architecture.

RISC architecture uses a small set of simple instructions for efficient processing.

Harvard architecture improves performance by using separate buses and memory for data and instructions

Von Neumann architecture uses a single memory space for both data and instructions.

Cache memory reduces the time to access data by storing frequently accessed information

Pipelining improves performance by overlapping the fetch, decode, and execute stages.

Multiple cores allow the CPU to execute tasks concurrently, improving performance.

Clock speed, measured in GHz, represents how many cycles the CPU executes per second.

Control instructions manage the execution sequence, including loops and conditional branches.

The MOV instruction copies data from one location to another

Branching instructions alter the flow of control in a program based on conditions.

Logical instructions manipulate data at the bit level using operators like AND, OR, and XOR.

Arithmetic instructions perform addition, subtraction, multiplication, and division.

The store stage places the result of the operation into memory or a register.

The execute stage performs the operation specified by the instruction

During the fetch stage, the CPU retrieves the instruction from memory.

The four primary stages are fetch, decode, execute, and store.

The status register (or flag register) stores flags used for conditional branching.

The stack pointer tracks the memory location of the top of the stack.

The IR temporarily holds the instruction being decoded and executed.

The MAR holds the memory address of data or instructions being accessed.
