RTEMS supports attaching interrupt handlers to hardware interrupt vectors, which is superior to the current approach of attaching handlers to signals. Direct attachment of handlers removes the execution overhead of converting hardware interrupts to signals and their subsequent propagation to the interrupt manager. It also removes the limitation of the number of hardware interrupts that can be supported under the signals model, as RTEMS is limited to 32 signals.
