    Study Notes

    CPU Components and Functions

    • The CPU (Central Processing Unit) is responsible for executing program code.
    • The control unit in a CPU retrieves and decodes instructions, generates control signals, and executes instructions.
    • Instructions are typically stored in the cache, a type of memory inside the CPU.
    • The floating point unit in a processor performs calculations that require decimal points.

    CPU Operations

    • After executing an instruction, the CPU sends the information to registers or memory for storage.
    • The CPU executes each instruction it fetches by decoding, executing, and storing the results.

    CPU Architectures

    • The architecture of a processor defines how it executes instructions, manages data, and interacts with other components.
    • The CPU is often referred to as the 'brains' of the computer system.
    • The arithmetic logic unit (ALU) in a processor performs mathematical and logical operations.

    RISC-Based Systems

    • RISC (Reduced Instruction Set Computing) systems are expected to become more popular in desktops and laptops.
    • RISC-based systems have an advantage over other systems due to their simpler and more efficient instruction set.
    • The main reason for using RISC-based systems is to improve performance and reduce power consumption.

    ARM-Based Processors

    • ARM-based processors are starting to be supported by Windows 11 operating system.
    • Apple systems are currently using ARM-based processors.
    • The use of RISC and ARM-based processors in desktops and laptops is expected to improve performance and reduce power consumption.

    Processor Comparison

    • X86 processors are associated with the IA-32 or Intel architecture 32-bit instruction set.
    • A 32-bit X86 processor can support up to 4 GB of memory.
    • X64 processors can run both 64-bit and 32-bit programs.
    • X64 processors are associated with brands like AMD and Intel.

    Power Consumption

    • RISC systems are known for their extended battery life and lower power consumption.
    • The use of RISC systems reduces power consumption and improves battery life.

    ARM Processors

    • RISC in ARM processors stands for Reduced Instruction Set Computing.
    • The ARM architecture is associated with the M1 series processors used in Apple desktops and laptops.
