1 all of the interruptor vertor table of nios is how to dispatch in the hardware address like the arm from 0x0 to 0xff?

Yes, similar but a little bit simpler than ARM... you only have the IRQ pin to which all the software and hardware interrupts are redirected!

??? There is an example at page 6-10 of the Nios II Software Developer&#39;s handbook...

some other examples should be in the examples directory of altera...

(just grepping gives some results

pj@TOM /cygdrive/c/altera/kits/nios2_51/examples/software
$ grep -rl alt_irq_register *
board_diag/board_diag.c
count_binary/count_binary.c
tcm/timer_interrupt_latency.c

); other examples (very similar to those available in the Altera Directory) are also available in the demo we distribute with ERIKA Enterprise, in particular the 2 CPU and the FIFO demo available here (http://www.evidence.eu.com/nios2/literature.asp)

What you mean with "stable names"? you can link a function you wrote to the interrupt using alt_irq_register...

4 who has the whole of the interrutor vertor table of nios, and he has the example of using it completed in the program?

There is only one exception vector, whose address is specified inside SOPCBuilder. Then, there is the ipending register, and all the rest is done in software...
