The ARM cores serve as a host for the Epiphany cores, roughly similar to the way an X86 CPU serves as a host to your video card. Epiphany is not ARM, it is a chip with a number of 1 GHz RISC cores that all communicate via a network-on-chip. So, it is optimized for doing a lot of floating-point arithmetic at very low power consumption.
