There are many instances where it is desirable or even essential to rapidly build a functional radio receiver to recover symbols from an unknown modulated source. The term ??rapid radio?? refers to a demonstrable analysis environment and receiver implementation methodology for rapid deployment. An automated tool for signal analysis requires several stages for the estimation and classification of the...
An analysis-based framework for the rapid development of a radio receiver for signals with unknown parameters is pro-posed, exploiting the reconfiguration capabilities of FPGAs. The framework guides a non-expert user through the process of signal classification and FPGA-based receiver implementation. System efficiency is traded off with implementation time in order to allow fast radio creation. A...
It is often desirable to change the logic and/or the connections within an FPGA design on-the-fly without the benefit of a workstation or vendor CAD software. This paper presents a dynamic router for Xilinx FPGAs, designed to run on stand-alone embedded systems. With information obtained from Xilinxpsilas XDL tool, a compact routing database for the Virtex-II/IIP/4 devices is built which only requires...
In systems typified by software defined radio, existing flows for run-time FPGA reconfiguration limit resource efficiency when constructing datapaths. We present the wires-on-demand framework that allocates a sandbox region in which modules from a library are flexibly placed and interconnected rapidly and autonomously in an embedded platform without vendor tools.
In systems typified by software defined radio, existing flows for run-time FPGA reconfiguration limit resource efficiency when constructing a variety of datapaths. Our approach allocates a sandbox region in which modules from a library can be flexibly placed and interconnected. An efficient run-time framework makes use of lightweight placement and routing techniques to respond on-demand to application...
