As I know, in order to resume a task, uC/OS-II copy the whole hardware stack to the external simulated stack. However, RTX51 tiny just preserve part content of hardware stack of a task,then ,how does tiny resume a task? Thanks in advance!
Actually the stack requirements in real applications are not as high as you imaging. Basically only the call/ret addresses are stored on the stack. With other words, stack was not an issue on several 1000 RTX TINY user applications in the past 12 years.
