[Haskell] Some old and quite old news.

[Serguey Zefirov]

I'd like to let dear readers to know that I finally managed to put 
source code and some documentation related to modeling of digital 
circuits and whole systems.

Most of the work was done in 2006 and 2007, so this is very old news. 
But I finally found time to put everything in more-or-less usable state 
and put it online (thanks to Max Taldykin, the host of Moskow HUG). I 
put it online a while ago so this is just old news.

The SVN repository is here: http://thesz.mskhug.ru/browser/hiersort

This is the model of multicore dynamic dataflow machine (with a twist), 
the draft paper about architecture under consideration and a 
presentation about the use of Haskell in modeling (almost) complete MIPS 
CPU with memory.

The core of our modeling framework is here: 
http://thesz.mskhug.ru/browser/hiersort/core/S.hs
The paper about dataflow machine is here: 
http://thesz.mskhug.ru/browser/hiersort/doc/sdd2.pdf
And the presentation is here: 
http://thesz.mskhug.ru/browser/hiersort/doc/hhm-eng.pdf

To summarize presentation content: we were able to deliver working model 
of MIPS CPU with working model of dynamic memory with memory controller 
in four months. The biggest roadblock encountered is the memory leak we 
couldn't get rid of. We often use Haskell to prototype various kinds of 
IP blocks and (parts of) computer architecture since that.
