Embedded System

• Embedded means something that is joined to
  something else. An embedded system can be thought
  of as a PC equipment system having programming
  embedded in it. An embedded system can be an
  autonomous system or it can be a piece of an
  expansive system. An embedded system is a
  microcontroller or chip based system which is
  intended to play out a particular assignment. For
  instance, a fire caution is an embedded system
  it will detect just smoke.
• A system is a course of action in which all its
  unit gather cooperate as per an arrangement of
  principles. It can likewise be characterized as a
  method for working, sorting out or completing one
  or numerous errands as indicated by a settled
  arrangement. For instance, a watch is a period
  showing system. Its segments take after an
  arrangement of guidelines to demonstrate time. In
  the event that one of its parts falls flat, the
  watch will quit working. So we can state, in a
  system, all its subcomponents rely upon each
  other.

Embedded System Has Three Components

• It has hardware.
• It has application software.
• It has Real Time Operating system (RTOS) that
  supervises the application software and provide
  mechanism to let the processor run a process as
  per scheduling by following a plan to control the
  latencies. RTOS defines the way the system works.
  It sets the rules during the execution of
  application program. A small scale embedded
  system may not have RTOS.

Characteristics of an Embedded System

• Single-worked - An embedded system more often
  than not plays out a specific activity and does
  likewise over and again. For instance A pager
  dependably works as a pager.
• Firmly compelled - All figuring systems have
  requirements on outline measurements, however
  those on an embedded system can be particularly
  tight. Plan measurements is a measure of a
  usage's highlights, for example, its cost, size,
  power, and execution. It must be of a size to fit
  on a solitary chip, must perform sufficiently
  quick to process information progressively and
  devour least energy to broaden battery life.

Characteristics of an Embedded System

• Responsive and Real time - Many embedded systems
  should ceaselessly respond to changes in the
  system's condition and should figure certain
  outcomes progressively immediately. Consider a
  case of an auto journey controller it constantly
  screens and responds to speed and brake sensors.
  It must figure quickening or de-increasing
  velocities more than once inside a constrained
  time a postponed calculation can bring about
  inability to control of the auto.
• Microchips based - It must be chip or
  microcontroller based.
• Memory - It must have a memory, as its product
  for the most part inserts in ROM. It needn't
  bother with any optional recollections in the PC.
  
• Associated - It more likely than not associated
  peripherals to interface info and yield gadgets.
• HW-SW systems - Software is utilized for more
  highlights and adaptability. Equipment is
  utilized for execution and security.

Processors in a System

• A processor has two basic units -
• Program Flow Control Unit (CU)
• Execution Unit (EU)
• The CU incorporates a bring unit for getting
  guidelines from the memory. The EU has circuits
  that actualize the guidelines relating to
  information exchange activity and information
  change starting with one frame then onto the
  next.
• The EU incorporates the Arithmetic and Logical
  Unit (ALU) and furthermore the circuits that
  execute guidelines for a program control errand,
  for example, interfere, or bounce to another
  arrangement of directions.
• A processor runs the cycles of bring and executes
  the guidelines in an indistinguishable grouping
  from they are brought from memory.

Types of Processors

• Processors can be of the following categories -
• General Purpose Processor (GPP)
• Microprocessor
• Microcontroller
• Embedded Processor
• Digital Signal Processor
• Media Processor
• Application Specific System Processor (ASSP)
• Application Specific Instruction Processors
  (ASIPs)
• GPP core(s) or ASIP core(s) on either an
  Application Specific Integrated Circuit (ASIC) or
  a Very Large Scale Integration (VLSI) circuit.

8
Microprocessor

• A microprocessor is a single VLSI chip having a
  CPU. In addition, it may also have other units
  such as coaches, floating point processing
  arithmetic unit, and pipelining units that help
  in faster processing of instructions.
• Earlier generation microprocessors
  fetch-and-execute cycle was guided by a clock
  frequency of order of 1 MHz. Processors now
  operate at a clock frequency of 2GHz

9
Microcontroller

• A microcontroller is a single-chip VLSI unit
  (also called microcomputer) which, although
  having limited computational capabilities,
  possesses enhanced input/output capability and a
  number of on-chip functional units.
• Microcontrollers are particularly used in
  embedded systems for real-time control
  applications with on-chip program memory and
  devices.
