Posted On May 22, 2019
design challenges of IoT are power efficiency, incompatible interferences and
compatibility with new processors. These design constraints can be addressed
with a Field Programmable gate array (FPGA).FPGA provide smooth interface with
the outside world, low power solutions and lowest latency which are ideal for
IoT applications. FPGA can connect with storage devices such as memories which
also allow for Bluetooth communication, Ethernet and wireless components. Most
of the IoT applications need a memory, networking chip such as BLE,Wifi,Zigbee,
processor core and a controller to actuate external devices. An FPGA can
interact with memory/storage devices through serialiser/deserialiser interfaces
(SERDES)12.FPGA take HTTP request packet received from a wireless Ethernet
component and decode its request, fetch/get required information from memory
and send back the requested result back through the Ethernet devices.
The FPGA can be
a replacement for the processor core in the IoT .If we require higher level of
processing ,the FPGA can be coupled with Advanced RISC Machines (ARM)
processors to get advantage of high level software functions such as web
servers. FPGA is a programmable special purpose
processors. It can handle signals at its input pins, process this signals and
send the signals on its output pins.

The sensor nodes
may rely on FPGAs, either based upon standalone platforms or as a combination
of FPGA and microcontroller. The low power optimized FPGAs can improve the
computation of several types of algorithms in terms of power consumption and
speed if we compare with the microcontrollers of commercial sensor nodes.
Moreover the architectures based on the combination of microcontrollers and
FPGA can play a major role in the future of sensor networks. They show
outstanding results in the processing capabilities like strong cryptography,
data compression 13, and self-testing. 14
