Embedded System
Meaning:- The system which is performed a & focused task in a constant time duration is called embedded system.
Ex:- washing machine , printer etc.
Processors / Controllers
It completes the task given by users with the help of software & hardware kits.
Normally controllers are used be caused it has in build own chip itself.
What is a Microcontroller?
It is an entire computer manufactured on a single chip.
It reduced the system complexity.
Specifications of Microcontroller
4 K bytes ROM
128 Bytes RAM
Two timer / counters (16 bit)
A serial port
Four general purpose parallel input/output port
It can address 64K of external data memory.
Indexed Addressing Mode
Use a register for storing the pointer and another register for offset.
Widely used for implementing look-up tables in code memory (Rom).
Effective address is the sum base+offset
Ex:- movc A, @A+DPTR
Register Set in 8051
A, B, R0 to R7 : 8 bit registers.
DPTR :16 bit register.
PC : Program Counter 16 bit register.
Stack pointer (SP).
PSW Program Status Word (Flags).
Special Function Registers (SFRs).
Robotics
The term means the artificial intelegancy made by the man.
It is the combination of computer science & electronics.
By uses of this intelegancy the machines performs the particular physical task.
Dc Motor
it is high speed & low torque motor.
Its speed vary from 9-12000rpm.
here we required high torque & low speed.
Speed can be controlled by the gears.
Ex:- CPU’s fan.
