3.10.6. Generic Interrupt Controller

The Generic Interrupt Controller (GIC) provided with the EB RTSMs differs substantially from that in the Emulation Board firmware. The programmer’s model of the newer device is largely backwards compatible. The model GIC is an implementation of the PL390 PrimeCell, for which comprehensive documentation is provided elsewhere. See PrimeCell® Generic Interrupt Controller (PL390) Technical Reference Manual.
