Microprocessors

• A microprocessor is a central processing unit (CPU) that contains the entire processing system of a computer on a single integrated circuit (IC).
• Components of a microprocessor include Arithmetic Logic Unit (ALU), Control Unit, Registers, and Bus.
• There are two main types of microprocessors: CISC (Complex Instruction Set Computing) and RISC (Reduced Instruction Set Computing).
• Microprocessor architecture can be classified into two main types: Von Neumann architecture and Harvard architecture.
• Microprocessor design considerations include performance, power consumption, and cost.

Computer Architecture

• Computer architecture refers to the design and organization of a computer's internal components, including the relationships between them.
• Components of computer architecture include Input/Output (I/O) devices, Memory (primary and secondary), CPU, and Bus.
• There are three main types of computer architecture: Von Neumann architecture, Harvard architecture, and Flynn's taxonomy.
• Flynn's taxonomy categorizes computer architecture into four types: SISD (Single Instruction, Single Data), SIMD (Single Instruction, Multiple Data), MISD (Multiple Instruction, Single Data), and MIMD (Multiple Instruction, Multiple Data).
• Computer architecture design considerations include performance, scalability, reliability, and cost.

Digital Circuits

• Digital circuits are electronic circuits that process and transmit digital information, represented as 0s and 1s.
• There are four main types of digital circuits: combinational logic circuits, sequential logic circuits, synchronous digital circuits, and asynchronous digital circuits.
• Components of digital circuits include logic gates (AND, OR, NOT, etc.), flip-flops, counters, and registers.
• Digital circuit design considerations include speed, power consumption, area, and cost.
