2. Field Programmable Gate Array (FPGA):
• FPGA is cluster of logic blocks which can be arranged by the
clients.
• The term ‘field programmable’ here implies that the device is
programmable outside the factory where it is fabricated.
• FPGA consists of I/O pins.
• Every one of I/O block gives independently selectable input, output
or bidirectional access to one of the general-purpose I/O pins on
the FPGA package.
• All logic gates are connected with each other by conducting
material known as channel.
• FPGA have 84 to 256 pins.
• With FPGA it is possible to integrate arithmetic and logic circuits,
controllers etc on the same device.

3. • A field Programmable Gate Array is a programmable logic device
(PLD) with higher logic densities and capable of implementing
different functions in a short period of time.
• In FPGA, the programmed configuration is usually volatile and
therefore needs to be reloaded whenever is applied or a different
functionality is required.
APPLICATIONS:
• FPGA is used for Digital Signal Processing (DSP).
• There are various applications of FPGA like video & image
processing, data processing and storage, speech recognition,
Bioinformatics, instrumentation and telecommunications, high end
RADAs etc.

4. FPGA Design and Programming:
• To defined the behavior of FPGA the user provides a hardware
description language (HDL) or a schematic design.
• Then, using electronic automation tool.
• Technology mapped net list is generated.
• The net list can then be fitted to the actual FPGA architecture using
a process called place and route.
• The user will validate the map, place and route result via timing
analysis, simulation and other verification methodologies.
• Once the design and validation process is complete, the binary file
generated used to configure the FPGA.
• FPGA architecture is shown in fig. 1

5. ADVANTAGES:
• FPGA is fast.
• FPGA is suitable for microprocessor.
• It is suitable for parallel data processing.
• Real time applications.
• Synthesis of FPGA is easier than ASCI.FPGA are suitable choice
for DSP or microcontrollers.
DISADVANTAGES:
• FPGA is slightly costly.
• It’s program is not easier.
• FPGA are generally slower than ASIC.
• FPGA can’t handle complex design.
• It draws more power.
