    Hi,
    it would be useful to remap the vector table.
    For example, each task or thread can have a different vector table.
    If the remap target is SRAM, a specific interrupt handler can be changed.
    From a power consumption aspect, less power is consumed if the vector is in SRAM than in Flash.
