Vanu, Inc has an interesting set of technical papers on their web site at


My favorite so far is "PC Clusters for Signal Processing: An Early
Prototype", which describes how they hooked up a variety of ordinary
PC's using Ethernet to spread the load of signal processing among a
cluster of processors.  In short, it worked fine, with the PCI bus's
bandwidth being the biggest constraint.

"Experiences Implementing GSM in RDL" is also interesting, as an
overview of the signal-flow and control-flow abstractions they are
building.  Their prototype ended up as an ungodly mess of C++, CORBA,
Java, and IDL, and the RDL looks a lot like the C++ abstractions
used in GNU Radio today.  But it's a step on the path to making 
interactively scriptable signal processing modules.

There are other papers there, that others may want to write reviews of.
