Default Interrupt Vector calculation based on MPC5534

I am working with Freescale MPC5534. ( the datasheet of MPC5534 )I am not able to understand how the address of a particular ISR is calculated during runtime. There are three registers involved, INTC_IACKR, INTC_IVPR, INTC_IVOR, and the final value of the interrupt vector corresponding to a particular ISR is based on the values loaded to these registers at runtime i.e, some base_address + prefix + offset from the three registers, respectively.

I am just not able to understand the connection these three values and how the vector is calculated from collective value of all these registers.

People who have worked on any PowerPC based controllers might be able to help.
