INTERRUPT/EXCEPTION STACK FRAME FOR A THREAD OR NESTED INTERRUPT
A stack frame of this structure is allocated for any interrupt or exception.
It goes on the current stack. If the RTOS has a system stack for handling
interrupts, every thread stack must allow space for just one interrupt stack
frame, then nested interrupt stack frames go on the system stack.
The frame includes basic registers (explicit) and "extra" registers introduced
by user TIE or the use of the MAC16 option in the user's Xtensa config. | 105 |
The frame size is minimized by omitting regs not applicable to user's config.
For Windowed ABI, this stack frame includes the interruptee's base save area,
another base save area to manage gcc nested functions, and a little temporary
space to help manage the spilling of the register windows.

NOTE ON SIMULATOR:
Under the Xtensa instruction set simulator, the frequency can only be estimated
because it depends on the speed of the host and the version of the simulator.
Also because it runs much slower than hardware, it is not possible to achieve
real-time performance for most applications under the simulator. A frequency
too low does not allow enough time between timer interrupts, starving threads.
To obtain a more convenient but non-real-time tick duration on the simulator,
compile with xt-xcc option "-DXT_SIMULATOR".
Adjust this frequency to taste (it's not real-time anyway!).
