TNKernel port for the ARM7/ARM9 CPU


Description



1. Operating

  TNKernel port for ARM works in the supervisor (SVC) mode.
  For the system tick counter, any avaliable timer may be used.  The typical interrupt tick time is 1..10 ms, but it is not mandatory.

2. Interrupt processing

   TNKernel port for ARM uses IRQ interrupt for the interrupt processing.
  The interrupt processing routine may use the VIC interrupt controller or  just perform a polling of an interrupt sources.
  TNKernel port for ARM do not allows nested interrupts.

    2.1. Interrupt Context switching

  When the CPU enters to the interrupt mode, it saves the context  registers in the interrupt stack (for TNkernel case - in the IRQ stack).
  The TNkernel context switch routine gets those registers from the IRQ stack and saves them in the interrupted task's stack.
