High-performance sound engine of guitar on optimal many-core processors

Abstract

This paper presents design space exploration of optimal many-core processors for physics-based sound synthesis of an acoustic guitar by quantitatively evaluating the impact of the sample-per-processing element (SPE) ratio, which is the amount of sample data directly mapped to a processing element (PE). This paper evaluates system performance in terms of execution time, area and energy efficiencies for high-performance sound engine of the guitar as the SPE ratio is varied. Experimental results indicate that the SPE ratio in the range of 2,756 (or PEs=24) to 11,025 (or PEs=96) provides the most efficient operation for synthesizing guitar sounds with 6-note polyphony sampled at 44.1 kHz. © Springer-Verlag Berlin Heidelberg 2014.
