Interesting and thanks for the clarification. This is not at all unreasonable and is very much along the lines of some of the work that I've found most interesting recently, namely Sing# and the Singularity Operating System. I'd be concerned about the overhead of layering such a system onto Windows, personally, but there's overhead in everything and systems continue to get faster so... who knows. I DO wonder, though... if the "high speed stuff" will be in C/C+ and assembler, and the signal processing core functions are (presumably written by you experts in this stuff and) designed to be self contained and separate from the GUI, then what's the advantage of using Erlang? YOU guys certainly know how to handle mutexes. Doesn't the major issue rapidly become the interface between the processing core and the display components? And if you can write the display components in choose-your-language, do you not wind-up with having to export SOME sort of locks from the processing core modules to serialize access to the exported information? I guess it all depends on what types of functions your design anticipates enabling in the GUI front end. I suspect that creating such a design will be a very difficult task if the result is to be something sufficiently flexible that it doesn't lock you in to a given graphical or functional paradigm. I'd suggest that, to be really useful, the design has to include not just the ability for somebody to write a GUI front end that looks like IK3VIG's design... but rather something on the order of the ability to create a GUI that included (for example) multiple sub-receivers within the passband, each with different filter widths, and each displayed in multiple ways (panadapter, waterfall, spectrum). I'm not saying this is a GUI I personally would want to write, but rather that this sort of thing should be possible in the functionally decomposed system. I dunno... maybe this isn't interesting or relevant to most folks on this reflector. Or perhaps it's too early in the process, or not up for discussion? It's very interesting in any case, de Peter K1PGV _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
