| v0.2.0 | 2014-09-20 Updated for github. Added AUTHORS, LICENSE, README, VERSION. The compiled tables file (oberon00.cgt) has been removed from the distribution. |
| v0.1.0 | 2004-10-31 Initial version as submitted to GOLD Parsing System's developer, Devin Cook (Devin@GOLDparser.org). Translated the Oberon-00 EBNF to a regular BNF in the GOLD parser style. |
Oberon-00 is a simple programming language proposed in [Wirth98] as a simple example of a common language that can be used for hardware and software compilation. Such language has been used for experimentation and research (establishing a proof-of-concept) purposes in the field of high-level synthesis (HLS) and as a testbed for hardware-software codesign. Oberon-00 is derived as a hardware-friendly subset of Oberon.
Oberon-00 has been used as a source language for describing simple programs that are mapped by a hardware compiler (namely hwcomp) to Xilinx XNF netlist format. hwcomp is an implementation of a hardware compiler inspired Wirth's hardware compilation article. The compiler was reportedly written in August 1998. The program is similar to the one described in the article by Niklaus Wirth. It takes a Pascal-esque/Oberon program as input and produces an XNF netlist as an output. The compiler has logic to generate all common operations: *, /, -, +, >=, <=, <, >, =.
The original source of the hwcomp project as well as the link to the source code download are now dead:
However, an archived link to the main webpage for this project has been made accessible:
This package contains both a regular BNF grammar derived from the Oberon-00 EBNF, which can be used within the GOLD parser environment and the original EBNF. It does not contain the hwcomp source code itself.
A former version of this file collection can also be downloaded from the GOLD Parsing System's website: http://goldparser.org
