Consequently, the dual-core Xilinx Zynq All Programmable SoC uses an ARM Generic Interrupt Controller (GIC) to process interrupts, which can come from:

  • Software-Generated Interrupts – 16 for each processor. Software-generated interrupts can interrupt themselves and either or both processors.
  • Shared Peripheral Interrupts – 60 in total. These interrupts can come from the I/O Peripherals in the Zynq SoC’s Processor System (PS) or from the Programmable Logic (PL) side of the device. The two ARM Cortex-A9 MPCore CPU’s share these interrupts.
  • Private Peripheral Interrupts – 5 interrupts, which are private to each CPU (e.g. CPU timer, CPU watchdog timer, and dedicated PL-to-CPU interrupt).
