Hi Element Thank you for your answer. I checked the device specifications from the ARM Cortex A8. And it have two Floating Point Units, a non-pipelined VFP-lite conforming to the IEEE754 standard for floating point arithmetic and a pipelined SIMD NEON coprocessor. Source: http://www.pandorawiki.org/Floating_Point_Optimization Its interesting that fluidsynth use CPU at 34% when nothing plays. The CPU itself is powerful. It runs PSX and N64 Emulation at fullspeed.
