Interrupt Handling

The Hawk ASIC, which controls the PHB (PCI Host Bridge) and the MPU/local bus interface
functions on the MVME5100, performs interrupt handling as well. Sources of interrupts may be
any of the following:

The Hawk ASIC itself (timer interrupts, transfer error interrupts or memory error
interrupts)

The processor (processor self-interrupts)

The PCI bus (interrupts from PCI devices)

The ISA bus (interrupts from ISA devices)

Figure 7-2

illustrates interrupt architecture on the MVME5100. For details on interrupt

handling, refer to the MVME5100-Series Single Board Computer Programmer’s Reference
Guide.
