Control plane interface

Yes, you will be able to run 2 different programs, one on each pair of cores (the details differ slightly from what you wrote, but it is really close enough).

Yes, you will have the source code (merely, mmap and memcpy).

Hi, Well, as I see: WE have to?! write a ultra light-weight operating system for Epiphany, not just for fun, but something useful. This is my mission?! for this 'year(s)'.
My (Xinu appr.) steps will be: 1) Learn about the HW (continuous), 2) Build toolchain (done), 3) Learn compiler's calling conventions (now), 4) Build bootstrap, 5) Polled in/output, 6) SEQ program, 7) Basic MMU, 8) Context switch, 9) Process management, 10) IT dispatcher, 11) RT clock functions, 12) tty driver, ... (new HW?!) ... 13) ETH + more device driver, 14) Port an FS, 15) Network port protocol(s), 16) Port a Shell and other applications.
I am an idealist, so there are some limits which are created by us. Regards, Gabor --- So, OS4E?! ---

Of course bare metal code would make optimal use of the Epiphany, but I think the point here is to obviate power-sucking CPUs. Taking the Epiphany from 'co-processor' to 'one processor to rule them all' would be a significant achievement. Btw, I'm guessing OS4E means OS for Epiphany?

Is develoment on the ARM cores possible ? I mean can I run the Epiphany compiler/linker and so on there or a host computer is necessary ?
