I am currently developing a version of the Astrobe IDE which hosts the Project Oberon FPGA RISC5 compiler on Windows.
With the work done so far I can now develop RISC5 Oberon software on Windows using all the Astrobe IDE features. When the edit / compile cycle is complete the resulting code can be synchronised with the Project Oberon system running on FPGA hardware via the RS232 connection.
A single Astrobe command (Build / Rebuild) can be used to automatically recompile ALL 23 core modules of the Project Oberon operating system - about 9000 lines in total. The whole process (including generating disassembly listings) takes less than 700 milliseconds on my PC.
The eventual aim is develop a minimal embedded version of the Project Oberon OS e.g. just the Kernel, loader, filesystem, SPI, RS232 and SD card support. As development is done on Windows the higher-level layers of the OS with the user-interaction features e.g. GUI, display, VGA, mouse, keyboard, compiler, editor etc will not be required. This should be easier to port to simpler FPGA development boards than those currently supported by the full Project Oberon OS.
When it is publicly released later this year the software will be made available for no cost. Anyone who is interested can get the latest progress reports and release announcements by following the forum "Astrobe for FPGA RISC5" on the Astrobe discussion forum:
