This is a no-frills port of uC/OS-II to the C40 dsp. I have included a
simple minded example program with tasks that delay and increment a
counter when they are running.  Timer 0, set to a 20Hz tick rate, is
used as the operating system timer. In a more complicated application,
the task stack sizes will have to be increased to allow for nested
interrupts.

There are many different hardware configurations out there, so I
assume a rather modest c40 with 2k of internal ram and 64k on the
local bus. The example program needs only 5k or so; just modify the
c40.cmd linker command file to match your hardware.  You get a
significant speedup by putting the task stacks in internal ram, but
this greatly restricts the maximum number of tasks, so I have left the
task stacks in local ram for now.

I developed this on linux using wine to run the TI compiler, hence the
mishmash of directory naming conventions in some of these
files. Nonetheless, I have tested and verified compilation with GNU
Make in a dos box under that other O/S. 

This documentation is rather sparse - if you have any questions or
find problems with this port (quite possible) feel free to contact me
via email. 

Enjoy,
