Intro to microprocessor and its detailing and applications
1. Introduction to Microprocessor
Block diagram of a computer system
Basic components of a computer system using block diagrams:
Cpu
Memory
Input and output unit
Evolution of microprocessor : 4,8,16,32 dan 64 byte
Nibble, byte, word dan longword
Fecthing and execution cycles.
Internal structure and basic operation of a microprocessor
(arithmetic and logic unit, control unit, register sets,
accumulator, condition code register, program counter, stack
pointer)
Bus system: data bus, address bus and control bus.
Microprocessor clock system
Examples of microprocessor: 8085, 8086.

A computer is a programmable machine that
receives input, stores and manipulates
data//information, and provides output in a
useful format.

5. Basic component of microcomputer
1.CPU - Central Processing Unit
the portion of a computer system that carries out
the instructions of a computer program
the primary element carrying out the computer's
functions. It is the unit that reads and executes
program instructions.
The data in the instruction tells the processor what
to do.

6. 2. Memory
Physical devices used to store data or programs (sequences of
instructions) on a temporary or permanent basis for use in an
electronic digital computer.
Computer main memory comes in two principal varieties: random-
access memory (RAM) and read-only memory (ROM).
RAM can be read and written to anytime the CPU commands it, but
ROM is pre-loaded with data and software that never changes, so the
CPU can only read from it.
ROM is typically used to store the computer's initial start-up
instructions.
In general, the contents of RAM are erased when the power to the
computer is turned off, but ROM retains its data indefinitely.
In a PC, the ROM contains a specialized program called the BIOS that
orchestrates loading the computer's operating system from the hard
disk drive into RAM whenever the computer is turned on or reset.

7. 3. I/O Unit
Input/output (I/O), refers to the communication between an
information processing system (such as a computer), and the outside
world possibly a human, or another information processing system.
Inputs are the signals or data received by the system, and outputs are
the signals or data sent from it
Devices that provide input or output to the computer are called
peripherals
On a typical personal computer, peripherals include input devices like
the keyboard and mouse, and output devices such as the display and
printer. Hard disk drives, floppy disk drives and optical disc drives serve
as both input and output devices. Computer networking is another
form of I/O.
