The TI processor was the TMS340x0 series. I had the "pleasure" of
coding for the both the 34010 and 34020.
 
TI's graphics library had a bug when compiled at full optimization. A
memory mapped register was not declared "volatile", so the compiler
would optimize out the read on a spin loop, and hang if the condition
was not met on initial loop.
