Applies to BORA Xpress

Introduction[edit | edit source]

BORA Xpress (also denoted as BoraX) is the top-class Dual Cortex-A9 + FPGA CPU module by DAVE Embedded Systems, based on the recent Xilinx "Zynq" XC7Z015 / XC7Z030 application processor. BORA Xpress offers great computational power, thanks to the rich set of peripherals, the Dual Cortex-A9 and the Artix-7 FPGA inside. BORA Xpress is designed in order to keep full compatibility with the ULTRA Line CPU modules, to guarantee the premium quality and technical value of those customers that require top performances.

The Hardware section provides detailed information about hardware interfaces and characteristics. This document will provide a functional overview of the module and will focus on system-related issues.
