Bubble NoC -- A Low Energy Network-on-Chip with Small Footprint and High Performance

Year: 2023

Authors: Carlstedt, Gunnar; Rimborg, Mats

Keywords: communication, networking and broadcast technologiescomponents, circuits, devices and systems, computing and processing, bufferless network, current injection, flow control, low energy, network-on-chip

The Bubble NoC is based on simplicity and provides outstanding performance. Flow control is implemented by bubbles, which are inserted between the flits. The logic resembles a traffic situation where a vehicle only moves if the next position is empty.
