In celebration of European π Day 22/7/2014, here is the new release 0.0k of XXICC.

 

Release 0.0k adds Flavia, described in this 'blog post: Flavia: the Free Logic Array.

 

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.

 

Until now, I've used Google Code as the location for XXICC downloads, wiki, and issues list.  Google Code recently stopped allowing new downloads.  Now that XXICC includes (fairly) usable hardware design tools, I figure it's appropriate content for element14.  The XXICC wiki and issues list will remain at Google Code for now: the link is xxicc.org. That's also the place to find earlier releases.

 

For an overview of XXICC, see the xxicc.org home page and wiki.  For details on the GalaxC programming language, XXICC Object Editor, and GalaxC extensions for Hardware Design (GCHD), here are the latest documents and complete code.

XXICC executable binaries rev 0.0k: executable XXICC binaries if you don't want to build from source code.

GalaxC sample/demo programs rev 0.0k: sample GalaxC programs and GCHD logic libraries.

GalaxC sample/demo program listings rev 0.0k: PDF listing of the sample GalaxC programs and GCHD examples.

Editable XXICC documentation files rev 0.0k: editable XOE files for XXICC documentation.

Installing and Running XXICC rev 0.0k: Document describing how to install and run XXICC.

Compiling and Running GalaxC Programs rev 0.0k: Document describing how to compile and run your own GalaxC programs.

 

Most of these files are stored in the element14 FPGA Group, for two reasons: (1) I can't seem to upload files to the Code Exchange, and (2) a main target technology for XXICC (and especially GCHD and Flavia) is FPGAs, so the FPGA Group is appropriate.  The last two files are at Google Code.

 

I've tested XXICC 0.0k on GNU/Linux (Ubuntu, Raspberry Pi Debian "Squeeze", Beagle Ångström) and 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.
