Here is the new release 0.0r of XXICC.  I've been horrifically busy with work and family obligations over the last two years so I wasn't able to keep up with XXICC.  Also, 0.0r is a major release since it adds integer nets and operators to GCHD, and can now program Lattice iCE40 FPGAs using the open-source IceStorm tools.  So there was lots of testing and documentation updates.


XXICC (21st Century Co-design) is a not-for-profit research project which attempts to bring digital hardware/software co-design into the 21st Century using an improved programming language and a Reduced Software Complexity philosophy.  Its goal is to make it easier and more enjoyable to write and maintain digital hardware and software. XXICC is pronounced "Chicken Coop", so-called because it has so many layers.


For an overview of XXICC, see XXICC: 21st Century Co-design.  For details on the GalaxC programming language, XXICC Object Editor, and GalaxC extensions for Hardware Design (GCHD), here are the latest documents and source code:

I've tested XXICC 0.0r on GNU/Linux (Ubuntu on x86 PCs and ODROID-C1 Ubuntu).  I haven't tested it yet on Raspberry Pi Raspbian or BeagleBone Debian.  I tested it on Windows 2000 and 7.  My main machine is Ubuntu, so the others are more likely to have anomalies.  Constructive comments and suggestions are most welcome.  I'd especially like to find out how to reproduce some of the bugs that have been eluding me.
