Zynq? UltraScale+? All Programmable MPSoCs provide up to 5X systemlevelperformance-per-watt compared to the Zynq-7000 SoC family.

ZynqUltraScale+ devices combine a high-performance ARM?-basedmulticore,mulTIprocessing system with ASIC-class programmable logic.

Dual- and quad-core applicaTIon processor equipped devices delivermaximum scalability, and are capable of offloading criTIcal applicaTIons,such as graphics and video pipelining, to dedicated processing blocks,along with a full complement of integrated peripherals and connectivitycores suitable for next-generation systems.

For the most compute intensive processing tasks, integratedprogrammable logic offers up to 100X performance improvement overprocessor-based implementations. The 16nm FinFET+ programmablelogic communicates with the processing system through 6,000 interconnects, enabling bandwidth that is not possible with multichipsolutions. Dramatic power savings are achieved through fine-grainedcontrol of power domains and gated power islands. With specializedprocessing elements for different workloads, ZynqUltraScale+ MPSoCsintegrate the right engines for the right tasks for next-generation
embedded challenges.
