Digital processing pool for JTRS software radio: in-mission flexibility and efficient technology insertion

This paper provides a summary of the main features of technical operation of a pool of processing platform, including: (1) switch fabric and system software supporting the maximum utilization of all processing resources for waveform and processing tasks as well as deterministic, wideband data communication simultaneous among all processing resources; (2) FPGA in-mission dynamic reconfiguration; (3) component-based middleware enabling 1 and 2 above; (4) support of software communications architecture (SCA) personalities; and (5) small form factor packaging. This paper also describes how these technical performance features support the needs of joint tactical radio system (JTRS) and software radio, including numbers of simultaneous waveforms and channels, scalability, flexibility, commercial off-the-shelf (COTS), technology insertion, economical spiral support, and low life-cycle cost.
