Honored Contributorhi,
how I can command a slave processor by another master processor using interruption: for example, the master processor can stop the slave processor. otherwise the slave processor awaits a signal from the master to become active. i can do this with NIOSII processor? can someone help me?? tks for all members.
Honored ContributorHave a look at the multiprocessor components in SOPC builder. If I remember correctly you have a mutex and a message box that can be used for that.
Honored ContributorHi,
I am trying to do an interruption at the execution of a program in C language. On SOPC Builder I a created a user_logic bloc with an irq output so that a niosII processor can react on this interruption. My problem is how and where can I add instructions (in C language) to do when this interruption occurs? Thanks for all help!Honored ContributorYou'll find functions in the HAL to install one of your own functions as interrupt handler.
Honored ContributorHi,
thank you Daixiwen for help. I found functions in the HAL. I had a look also to files generated by the NIOS II IDE in "hello_world_3_syslib" and I found this file:"alt_irq_handler.o". What I understood is that the compiled default file which is handling interruptions is "alt_irq_handler.c" and if I wanted to write IRQ code, it should be there and not by creating my own function as interrupt handler. Isn't it? Am I in the right way of thinking? If I am, in my situation, I cannot change this file to see the result, because I am not in administrator session. What can I do? Thanks a lot!Honored ContributorYou must write your own function and register it with alt_irq_register(). You don't need to edit the system library. Have a look at the alt_irq functions in the hal api (http://www.altera.com/literature/hb/nios2/n2sw_nii52010.pdf) reference.
