A Case Study on Multi-Softcore Aided Hardware Architectures for Powerline MAC-Layer
Powerline communication is a promising technology
for connecting Internet of Things (IoT) applications, where
devices have strict limitations regarding available installation
space and power dissipation. Especially the wiring of these devices
benefits from not having additional cables for network connection.
Thus, saving costs and additional installation effort. In this paper
a very resource-efficient implementation of a HomePlug 1.0.1
[5] compatible powerline MAC layer, which is used to control
the data flow and link status of a powerline connection, is
presented. The MAC layer is implemented in two variants, using
state machines and softcore processors. A comparison of the
two approaches shows that the softcore design used up to 78 %
less FPGA ressources and is superior in terms of flexibility and
maintainability
