dc.description.abstract | Many current system-on-chip (SoC) devices are composed of low-power multicore
processors combined with a small graphics accelerator (or GPU) offering a trade-off
between computational capacity and low-power consumption. In this context, spatial
audio methods such as wave field synthesis (WFS) can benefit from a distributed
system composed of several SoCs that collaborate to tackle the high computational
cost of rendering virtual sound sources. This paper aims at evaluating important
aspects dealing with a distributed WFS implementation that runs over a network of
Jetson Nano boards composed of embedded GPU-based SoCs: computational per
formance, energy efficiency, and synchronization issues. Our results show that the
maximum efficiency is obtained when the WFS system operates the GPU frequency
at 691.2 MHz, achieving 11 sources-per-Watt. Synchronization experiments using
the NTP protocol show that the maximum initial delay of 10 ms between nodes does
not prevent us from achieving high spatial sound quality. | es |
