SParrow-NEST Overview

This version combines all board-support and signal-processing capabilities of the SParrow-ZedMate along with an array of additional DSP/Arithmetic functions like square-root, CIC filters, more NCO options etc. The SParrow-NEST is an optimal choice for generating DSP algorithms targeted for high sample-rate applications in which much of the front-end processing need be done in hardware before bringing down the sample-rate.

The SParrow-Nest is a licensed version of SParrow with 1-year license validity. This Version is an optimum choice for DSP System developers in implementing medium/high sample-rate DSP front-end processing in hardware using its rich set of leaf-library components including CIC filters, Square-Root, advanced NCOs/Moving-averages etc. The SParrow-Nest also includes all the board-support and quick prototype development capabilities of the SParrow-ZedMate version. The generated code-base, which includes the RTL and the C-code, can be used even beyond the expiry of the license.


With this version, the users can quickly prototype a signal-processing system using XILINX® Zynq AP-SOC based ZedBoard or ZC702 along with ADI’s AD9467-FMC-250EBZ HS-ADC board. The SParrow-NEST library includes all board specific components supported by SParrow-ZedMate. All related driver, DMA-setup, ISR setup and other software initialization codes can also be generated using SParrow-NEST.

The IPs generated using SParrow can be easily integrated along with other 3rd party DSP blocks (like XILINX® LogiCORE™ IPs) on any ARM AMBA AXI4 based switch-fabric, using the standard AXI4-Lite programming and AXI4-Stream sample-stream interfaces

The Driver and Algorithm codes generated by the tool have easy-to-use APIs that enable seamless integration into other applications if needed. The tool also provides an intuitive way for feeding the initialization of parameters (like FIR coefficients, control register values etc.) and the hardware initialization sequence, in a simple script format.
