This paper describes the demonstration of a four-channel digital beamforming system incorporating highly integrated silicon germanium downconverter modules. The downconverter modules are designed to translate X-band frequencies (9 to 10.5 GHz) down to a common 1.0 GHz IF output. The modules were integrated with an X-band antenna array and high-speed(More)
Managing the buffering of data along arcs is a critical part of compiling a synchronous dataflow (SDF) program. This paper shows how dataflow properties can be analyzed at compile-time to make buffering more efficient. Since the target code corresponding to each node of an SDF graph is normally obtained from a hand-optimized library of predefined blocks,(More)
