Introduction

BORA is the new top-class Dual Cortex-A9 + FPGA CPU module by DAVE, based on the recent Xilinx Zynq XC7Z010/XC7Z020 application processor. Thanks to BORA, customers are going to save time and resources by using a compact solution that includes both a CPU and an FPGA, avoiding complexities on the carrier PCB. The use of this processor enables extensive system-level differentiation of new applications in many industry fields, where high performances and extremely compact form factor (85mm x 50mm) are key factors. Smarter system designs are made possible, following the trends in functionalities and interfaces of the new, state-of-the-art embedded products. BORA offers great computational power, thanks to the rich set of peripherals, the Dual Cortex-A9 and the Artix-7 FPGA together with a large set of high-speed I/Os (up to 5GHz). BORA enables designers to create rugged products suitable for harsh mechanical and thermal environments, allowing the development of the most advanced and robust products. Thanks to the tight integration between the ARM-based processing system and the on-chip programmable logic, designers are free to add virtually any peripheral or create custom accelerators that extend system performance and better match specific application requirements. BORA is designed and manufactured according to DAVE Ultra Line specifications, in order to guarantee premium quality and technical value for customers who require top performances and flexibility. BORA is suitable for high-end applications such as medical instrumentation, advanced communication systems, critical real-time operations and safety applications.
