Epiphany III is a manycore featuring 16 RICS CPU cores which is part of the Parallella board. The epiphany’s cores (eCores) are connected by a low-latency 2D mesh Network-on-Chip.
An ARM based processor Zynq-7000 SoC drives the Parallella board, this processor has its Ubuntu version called Parabuntu. There is a flat shared 1GB DDR3L SDRAM memory map that can be access by the whole board with a latency that avoids it usage for real-time purposes.
Each eCore has a local memory of 32KB that can be accessed by the eCore itself (in a single cycle) and the rest of eCores (adding the NoC delay to the access). Every eCore will have an instance of the M2OS running.
The webpages of Adapteva and Parallella can be checked for more information.
The version of M2OS for manycores (M2OS-mc) can be used with the Epiphany III board. More details in the “M2OS in Epiphany User’s Guide”:
