The authors design a very small, packet-switched, clock-less Network-on-Chip (NoC) as a replacement for the existing crossbar-based communication infrastructure in a commercial audio DSP chip. Both solutions are laid out in a 0.18 um process, and compared in terms of area, power consumption and routing complexity. Even though the NoC turns out to be larger and more power consuming than the existing crossbar implementation, it still accounts for less than 1% of the total chip area and power consumption, and is justified by a long list of advantages: the NoC is modular, scalable, and in contrast to the existing crossbar, it allows all blocks to communicate.
