SAM7X calling function from interrupt

I am trying to use a timer interrupt to "Set up" a function call. INstead of setting a flag in the interrupt and then polling that flag I would like the interrupt to call a function as soon as teh interrupt is done, but not during the interrupt.
I tried setting a software (swi) interrupt to fire during the timer interupt, but the problem was that it called the software int immediatley during the timer IRQ and not after. I thought the swi was a lower priotrity int then the timer IRQ (set to priority 7), But I guess not...am I wrong????
Is ther a way to do this?
Possibley use a lower priority IRQ to call a function by "Setting" that IRQ during a higher priority IRQ ?
