Notification of Availability of Software Framework, Warped Alloy, for Software Defined Radio (SDR) Signal Chain

The Department of the Army is pleased to announce the availability of a cutting-edge software framework designed to enhance the capabilities of Software Defined Radio (SDR) systems. This framework enables the SDR signal chain to dynamically adjust its capabilities based on the sensed RF environment and to respond at the protocol level in real-time. The Department of the Army is releasing this software framework to foster collaboration with industry partners and encourage the integration of this technology into their SDR products. The intent is to enable greater flexibility in conducting radio frequency operations, allowing industry partners to leverage this framework to enhance their SDR systems' adaptability and operational effectiveness. By providing this framework, we aim to advance the state of SDR technology and promote innovation in the field of radio frequency operations. Key Features of the Framework: Rapid Reconfiguration: The framework allows for swift reconfiguration of the RF signal processing chain modules within the SDR’s field programmable gate array (FPGA), ensuring adaptability to varying operational requirements. FPGA-Based Physical Layer (PHY) and Media Access Control (MAC): The framework enables the rapid development and implementation of a fully-customized PHY and MAC layer that supports various signals and waveforms, providing a comprehensive solution for SDR applications. Elements Available for Industry: FPGA Top-Level Framework: This top-level hardware description language (HDL) framework resides within the SDR FPGA, facilitating seamless communication between the General-Purpose Processor (GPP) and the signal modules. Application Programming Interface (API): A user-friendly, common C-based API is provided, allowing developers to create SDR-agnostic applications that can manipulate the programmed signal FPGA modules effectively. Transport Interface (TI): The TI consists of dynamic or static C libraries utilized during application builds, enabling efficient message transport to and from user-based applications and FPGA signal modules. Exemplar Data Generation/Consumption Module: This module serves as a testing tool for hardware-specific implementations of the framework, ensuring compatibility and performance validation. Documentation: Comprehensive documentation will be made available, including development environment guides and a developer's guide, to assist industry partners in effectively utilizing the framework. The Department of the Army encourages industry partners to engage with this innovative framework, which is expected to significantly advance the capabilities of SDR technology. The Government retains all rights of modifications made to the original framework.
