The Zynq?-7000 family is based on the Xilinx All Programmable SoC architecture. These products integrate a feature-rich dual-core or single-core ARM? Cortex?-A9 based processing system (PS) and 28 nm Xilinx programmable logic (PL) in a single device. The ARM Cortex-A9 CPUs are the heart of the PS and also include on-chip memory, external memory interfaces, and a rich set of peripheral connectivity interfaces.

The Zynq-7000 family offers the flexibility and scalability of an FPGA, while providing performance, power, and ease of usetypically associated with ASIC and ASSPs. The range of devices in the Zynq-7000 family allows designers to targetcost-sensitive as well as high-performance applications from a single platform using industry-standard tools. While eachdevice in the Zynq-7000 family contains the same PS, the PL and I/O resources vary between the devices. As a result, theZynq-7000 and Zynq-7000S SoCs are able to serve a wide range of applications including:

? Automotive driver assistance, driver information, and infotainment

? Broadcast camera

? Industrial motor control, industrial networking, and machine vision

? IP and Smart camera

? LTE radio and baseband

? Medical diagnostics and imaging

? Multifunction printers

? Video and night vision equipment

The Zynq-7000 architecture enables implementation of custom logic in the PL and custom software in the PS. It allows forthe realization of unique and differentiated system functions. The integration of the PS with the PL allows levels ofperformance that two-chip solutions (e.g., an ASSP with an FPGA) cannot match due to their limited I/O bandwidth, latency,and power budgets.

Xilinx offers a large number of soft IP for the Zynq-7000 family. Stand-alone and Linux device drivers are available for theperipherals in the PS and the PL. The Vivado? Design Suite development environment enables a rapid productdevelopment for software, hardware, and systems engineers. Adoption of the ARM-based PS also brings a broad range ofthird-party tools and IP providers in combination with Xilinx’s existing PL ecosystem.

The inclusion of an application processor enables high-level operating system support, e.g., Linux. Other standard operatingsystems used with the Cortex-A9 processor are also available for the Zynq-7000 family.

The PS and the PL are on separate power domains, enabling the user of these devices to power down the PL for powermanagement if required. The processors in the PS always boot first, allowing a software centric approach for PLconfiguration. PL configuration is managed by software running on the CPU, so it boots similar to an ASSP.

The Zybo (Zynq? Board) is a feature-rich, ready-to-use, entry-level embedded software and digital circuit development platform built around the smallest member of the Xilinx Zynq-7000 family, the Z-7010. The Z-7010 is based on the Xilinx? All Programmable System-on-Chip (AP SoC) architecture, which tightly integrates a dual-core ARM Cortex-A9 processor with Xilinx 7-series field programmable gate array (FPGA) logic. When coupled with the rich set of multimedia and connectivity peripherals available on the Zybo, the Zynq Z-7010 can host a whole system design. The on-board memories, video and audio I/O, dual-role USB, Ethernet and SD slot will have your design up-and-ready with no additional hardware needed. Additionally, six Pmod connectors are available to put any design on an easy growth path. The Zybo provides an ultra-low cost alternative to the ZedBoard for designers that don’t require the high-density I/O of the FMC connector, but still wish to leverage the massive processing power and extensibility of the Zynq AP SoC architecture.
