XXICC (21st Century Co-design) release 0.0n

johnbeetem
johnbeetem
20 Jan 2015

Here is the new release 0.0n of XXICC, which adds Xilinx Spartan-6 Flavia implementations for the ValentF(x) LOGI-Pi board and LOGI-Bone.

 

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 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.

 

Release notes for XXICC rev 0.0n

Programming in the GalaxC Language rev 0.0j: reference and user guide for the GalaxC programming language, unchanged for 0.0n.

The XXICC Anthology rev 0.0n: collection of miscellaneous XXICC topics, including user guides for the XXICC Object Editor, GCHD and Flavia.

Data files for FlaviaP32 release 0.0n: Data files for the FlaviaP32 implementation of the Free Logic Array for the Papilio One 250K.

Data files for FlaviaP48 release 0.0n: Data files for the FlaviaP48 implementation for the Papilio One 500K.

Data files for FlaviaLP56 release 0.0n: Data files for the FlaviaLP56 implementation for the ValentF(x) LOGI-Pi.

Data files for FlaviaLB56 release 0.0n:  Data files for the FlaviaLB56 implementation for the ValentF(x) LOGI-Bone.

Taming the Wild Bitstream (unchanged for 0.0n): Supplement to Flavia: the Free Logic Array.

XXICC code release 0.0n: all source code for XXICC.

XXICC source code listing rev 0.0n: source code listing in PDF.

XXICC executable binaries rev 0.0n: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, unchanged for 0.0n.

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

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

Installing and Running XXICC rev 0.0n: 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, unchanged for 0.0n.

 

I've tested XXICC 0.0n on GNU/Linux (Ubuntu, Raspberry Pi Debian "Wheezy", BeagleBone Debian, and BeagleBoard 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.

    Nice update John. Do you have an end project that you intend to implement with the board or are you just looking at options to make it useful? DAB

    The Papilio One works great with ODROID-C1 now.  To fix the "Raspberry Pi Effect" I hooked up a USB 1.1 hub to ODROID-C1's OTG port.  OTG uses a separate controller from the four USB A ports, so by keeping the high-speed USB 2.0 devices on the A ports and the low/full-speed USB 1.1 devices on the OTG port, there are no split transactions and thus no missing or repeated characters.

     

    Connecting the Papilio One to the USB 1.1 hub fixed the slow USB transfer.  I think it was slow because acknowledge packets were getting lost so the USB 2.0 controller had to recover and retransmit.  By going through the USB 1.1 hub and OTG there are no packets lost and I can download the Papilio One 250K FPGA in a couple tenths of seconds just like on my x86 PC.
