Hello,
I am the lead engineer on the Nucleus Plus RTOS. One of my coworkers asked me if I knew any processors that had a stack that grows up. The only one I knew of, for sure, was the Intel i960. We have a fair amount of code in our system that accommodates stacks that grow up. If we can't find a reasonable number of processors who's stack does grow up we will remove that code.
