Field
Programmable Gate Array (FPGA)
•FPGA is
field programmable gate array.
•FPGA are PLDs which are made from
interconnected small
macro cells.
•It is
made from logic
cells.
•Logic
cells are connected each other by horizontal and vertical channel.
•Each
logical cell is having a complicated design.
•These
logic gates are made from NAND
gates.
•They
are thousands
in number.
•You
can make anything using FPGA like you can make it a microcontroller or you can make it digital signal processor or any thing.
•FPGA consist of various I/o pins.
•I/o
pins connects the chip to the outside world.
•All the logic gates are connected to
each other via channel these channel are made from conducting metal.
•The
channels are matrix
in shape.
•With FPGA it is possible to integrate multiple storage registers, arithmetic and logic circuits, controllers etc. on the same device.
•FPGA is a very flexible chip.
•FPGA is a volatile device.
•It clear everything when the power supply
is removed.
•FPGA have 84 to 256 pins.
WHAT ARE FPGAs USES ?
•FPGA is use for High Performance Computing.
•FPGA is use for Digital Signal Processing (DSP).
•FPGA is use for Phase-locked loops.
•FPGA is use for Routers.
•FPGA is use for Video & Image Processing.
•FPGA is use for High-end RADARs.
•FPGA is use for Speech recognition.
•FPGA is use for ACSI prototyping.
•FPGA is use for Bioinformatics.
WHAT ARE FPGAs ADVANTAGES ?
•Make
anything like DSP or Microcontroller.
•It
is too fast.
•Programmable.
•Shorter time to market.
•FPGA
are suitable choice for microprocessor.
•Efficient
system.
•Parallel
data processing.
•Update
feature from customer site.
•Real
time applications.
•Synthesis
is easier than ASCI.
WHAT ARE FPGAs DISADVANTAGES ?
•Its
cost is very high.
•Not
optimize for power consumption.
•It
is very complicated.
•Programming
is difficult.
•Volatile.
•Large
number of pins.
•Slow
design software.
•Don't
provide fix delay.
