Download

SHAP and its toolchain will gradually be published as open source on this site. Currently, synthesized SHAPs are offered for a selection of FPGA prototyping boards together with example applications.

Additional sources not yet published may be inquired for research and educational purposes. Please, provide some references to your research and/or educational activities with your request.

Requirements

For playing with SHAP, you will need one of the supported or a compatible FPGA prototyping board. At the minimum, you need to be able to program the FPGA upon it and establish a serial communication with the board to upload the application and observe its console output. Many applications will only make sense with the additional connection of an input device (PS/2 keyboard or mouse), an output device (VGA monitor) or another general purpose communication (USB, ethernet).

The downloadable content offered on this page is subject to differing license terms! Third-party licenses as applying for some parts of the runtime implementations are indicated with the download offer. All other content (bitstreams, tools, demonstrations, etc.) is provided with NO WARRANTY whatsoever. It is free of charge for personal, research and educational use only. Please, feel free to contact us if you intend a commercial application.

The format of the .shap files has changed per June 4. Please, update your local copies of .bit files, .shap files, the ShapLinker as well as the run time.

Applications

After programming your board with SHAP, you may upload a prelinked SHAP application over the serial link as detailed in the User Manual.

Application Building

For writing your own SHAP application, you need a regular set of Java development tools, the SHAP runtime (2008-06-05) [→ JavaDoc] and the ShapLinker (2008-06-04). Use our Feature Test if you do not have your own application handy.

The process of compiling and prelinking is described in the User Manual.

Note that third-party licenses apply to parts of the runtime implementation: The implementation of the core CLDC runtime is based on the MR1 implementation by the phoneME project, which has been realeased under the GPL 2.0. The included soft floating-point emulation is a Java port of John Hauser's SoftFloat library by the JOP project, which is open-source but not free for commercial use!


Sources

We publish the source code of the core CLDC runtime implementation used by SHAP and as derived from the phoneME implementation in the fulfillment of our obligations according to the GPL 2.0.

Ticker

New version (2008-06-04) of SHAP as well as the new game SkyRoads are now available for download.
