Vectored Interrupt Controller

Recommended for:

  • Device: Cyclone® V

  • Quartus®: Unknown



This design example shows how to use the Vectored Interrupt Controller (VIC) with a Nios® II processor in a system design. The VIC provides a higher performance alternative to the default internal interrupt controller (IIC) of the Nios II processor.

The hardware design shows how to hook up a VIC with the Nios II processor. The software example shows how to use the Hardware Abstraction Layer (HAL)-enhanced interrupt application programming interface (API) to register an interrupt handler for a system based on the VIC component. The VIC can be daisy-chained as well if more than one VIC is required in the system.
