Q. What is SPI?
Ans: The Serial Peripheral Interface (SPI) bus is a synchronous serial communication
interface specification used for short distance communication, primarily in
embedded systems. The interface was developed by Motorola.
This topic deals with the SLOT ANTENNAS types and 3-D microwave reflection
tomography. The design and test of microstrip slot antenna array for 3D microwave
imaging for the structural assessment of concrete structure is presented in this paper.

What is SPI ?
The Serial Peripheral Interface or SPI bus is a synchronous serial data link, a de facto standard, named by
Motorola, that operates in full duplex mode.
It is used for short distance, single master communication.
The LPC2141/2/4/6/8 I2C interfaces are byte oriented, and have four operating
modes: master transmitter mode, master receiver mode, slave transmitter mode
and slave receiver mode.
->During a data transfer from a master transmitter to a slave r

I2C Register Descriptions:-
In I2c is having 7 registers:-
->1. I2C0CONSET :- Control set Register
->2. I2C0CONCLR :- Control clear Register
->3. I2C0DAT :- Data Register
->4. I2C0STAT :- status Register
->5. I2C0ADR :- Slave address Register
Introduction about I2C (Inter Integrated circuit) :-
->Almost 25 years ago , in the early 1980's philips designed & developed
a new bus standard namely I2C bus, for easy communication between Integrated circuit.

A very important step in physical design cycle.
A poor placement requires larger area.
Also results in performance degradation.
It is the process of arranging a set of modules on
the layout surface.
