The document outlines the functions and components of microprocessors and microcontrollers, detailing their roles in processing data and governing specific operations in embedded systems. It highlights essential aspects such as the arithmetic logic unit (ALU), control unit, and differences between microprocessors and microcontrollers, as well as architectural distinctions like von Neumann and Harvard models. It also includes multiple-choice questions related to the content covered.

2. Microprocessor
• A microprocessor is a computer processor which
incorporates the functions of a computer's central
processing unit (CPU) on a single integrated circuit (IC)
• Accepts binary data as input, processes it according to
instructions stored in its memory and provides results
(also in binary form) as output

3. Brain of Microprocessor
• ALU performs all arithmetic and logical operations on the
data received from input devices or memory.
• Register array consists of a series of registers like
accumulator (A), B, C, D etc. which acts as temporary fast
access memory locations for processing data.
• Control unit controls the flow of instructions and data
throughout the system.

6. Microcontrollers
• A microcontroller is a compact integrated circuit
designed to govern a specific operation in an
embedded system.
• A typical microcontroller includes a processor,
memory and input/output (I/O) peripherals on a single
chip.
