Wider coverage of observation missions will increase
onboard power restrictions while, at the same time, pose higher
demands from the perspective of processing time, thus asking for
the exploration of novel high-performance and low-power processing
architectures. In this paper, we analyze the acceleration
of spectral unmixing, a key technique to process hyperspectral
images, on multicore architectures. To meet onboard processing
restrictions, we employ a low-power Digital Signal Processor
(DSP), comparing processing time and energy consumption with
those of a representative set of commodity architectures. We
demonstrate that DSPs offer a fair balance between ease of
programming, performance, and energy consumption, resulting
in a highly appealing platform to meet the restrictions of current
missions if onboard processing is required. [-]
