Zynq-based, Agile SDR Solution

NutaqZeptoSDR

Nutaq ZeptoSDR

Nutaq’s ZeptoSDR is a fully packaged, agile SDR solution comprised of the Zynq-based Zedboard

and the Nutaq Radio420S, which also supports GNU Radio.

The ZeptoSDR is for developers who want to:

• Develop a complete software defined radio solution,

targeting the UHF Band.

• Utilize a powerful yet low power Zynq-based

Zedboard solution.

• Shorten external-to-embedded host migration time

using Nutaq’s identical APIs.

• Use a high performance, shielded radio to target

a wide frequency range.

• Accelerate their development cycle using

the GNU Radio development environment.

• Achieve accuracy and time savings provided

by an auto-calibrated radio solution.

• Utilize a robust, packaged, air-cooled portable

SDR system.

• Benefit from collaborative development with

the Zedboard and GNU Radio communities.

Waveform developers using the ZeptoSDR have access

to the many benefits offered by the tightly coupled dual

core ARM Cortex-A9 and the Artix-7 series FPGA on the

Zynq-7020, which will allow them to:

• Target the Xilinx Artix-7 FPGA for intensive processing

such as down-conversion, up-conversion, and other

PHY layer elements such as OFDM.

• Target The SoC’s Dual Core ARM Cortex-A9 for the

upper protocol layers.

• Exceed the performance of a discrete FPGA-processor

solution, achieving higher bandwidth with

lower latency.

For those intending to use the Zynq-7000 series for

deployment purposes, the Zynq enables low cost, low

power solutions which will ultimately yield a cheaper

BOM cost and faster NRE cycles.

Software Key – FeaturesNutaq Board Support Development Kit (BSDK)

Nutaq’s BSDK is a suite of tools which significantly

reduces the time spent on low value-added tasks such

as programming interfaces, adjusting FPGA constraints,

debugging Host drivers, etc.

The suite includes:

• Radio logic interfaces (in the Artix-7) and calibration

routines (in the ARM Cortex-A9)

• Development frameworks

• Identical external and embedded APIs

• CCE (Communication Control Engine) Application that

interprets API calls from the host and maps them

to the associated embedded API calls.

• Linux external host drivers

• Real Time Data Exchange (RTDEx), which is an efficient

Linux based data-streaming API between the external

host and the ARM Cortex-A9

• Application examples

ZeptoSDR GNU Radio Plug-In

The ZeptoSDR features seamless integration to the GNU

Radio model-based design tool, combining a graphical

development environment (or Python script commands)

and automatic code generation. Using GNU Radio can

greatly accelerate the development of applications,

shorten the development cycle and reduce project costs.
