Software targeting general purpose processing (GPP) elements has been successfully reused for software defined radio (SDR) platforms in support of low-bandwidth waveforms. The Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA) promotes reuse of GPP-based software by providing a consistent framework for developing reusable waveform implementations. However, high-bandwidth waveforms, such as those used in above 2 GHz MILSATCOM terminals, overwhelm the capabilities of GPP-only radios making field programmable gate arrays (FPGAs) a necessity in high-bandwidth radio systems. The SCA does not address the development of reusable FPGA-based waveform implementations. This paper presents an approach extending the current SCA to address FPGA-based platforms using System-on-a-Chip (SoC) best practices for design reuse, including common interfaces and a robust system simulation environment.
Kevin Skey is currently the Director of MITRE’s Programmable Radio Technology Laboratory and Principal Investigator for Emerging Technology for VLSI IR&D project. His professional experience ranges from the lead role to individual contributor for the design and implementation of DSP-based hardware and embedded software architectures for wireless communications, RADAR, GPS and telecommunication systems. He also continues to develop custom CAD/CAE methodologies for SoC, FPGA and embedded software systems. In the past, he has been involved in the specification and design-to-production of several high volume consumer and industrial products as well as the development and fielding of numerous advanced prototype systems. Kevin has also worked for Advanced Microsystems Corporation, MIT/LL, Northstar (Brunswick), Advanced Fibre Communications (Tellabs) , and Synopsys.
