GR712RC
1.4 Interrupts
The following table specifies the interrupt assignment for the GR712RC.
The interrupts are routed to the IRQMP interrupt controller and forwarded to the LEON3FT proces-
sors. Interrupt 16-31 are generated as interrupt 12 and for those interrupts a chained interrupt handler
is used.
1.5 GRLIB IP cores
The GR712RC uses the following cores from the GRLIB IP library:
