Parallella Hardware

Introduction


The key features of the Parallella board are: a Xilinz Zynq SoC which provides a Dual ARM® Cortex™-A9 processor plus programmable logic, 16 or 64-core Epiphany floating-point accelerator (32/100 GFLOPS), high bandwidth expansion via daughter cards, and interfaces that include Gigabit Ethernet, HDMI and MicroSD.

Kickstarter
The initial run of Parallella computers is being funded via a Kickstarter campaign, which on 27th October 2012 had succeeded in raising $898,921 via 4,965 backers, and with those pledging $99 or more receiving at least one board.

Thanks to generous support from Xilinx the Kickstarter boards will be upgraded to use a Zynq-7020 SoC instead of a Zynq-7010.

General availability
Adapteva are taking pre-orders of the Parallella computer for October 2013 delivery.

Prototype
The first Parallella prototypes shipped in late December 2012 and comprise of a ZedBoard plus a 16 or 64-core Epiphany FMC.

From a software perspective the prototypes are virtually identical to the final form factor boards.

Beta (Gen0)
The first 10 Parallella beta boards came back from assembly on 11th April 2013 and were unveiled four days later at the Linux Foundation Collaboration Summit.

In July 2013 22 Gen0 boards went out Kickstarter backers, and a further 18 to key project contributors.

Backers who were due to receive a board but who opted to wait a little longer will receive a Gen1 board upgraded with a 64-core Epiphany co-processor.

Final (Gen1)
The first Gen1 boards went to manufacture in August 2013.
