Interrupt Controller interface provides full support for programmable edge triggered (rising, falling) or sensitive, compatible with Interrupt Controller Specification. Through its INTC compatibility, it provides a simple interface to a wide range of low-cost devices. INTC IIP is proven in FPGA environment. The host interface of the INTC can be simple interface or can be AMBA APB, AMBA AHB, AMBA AHB-Lite, AMBA AXI, AMBA AXI-Lite, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
INTC IIP is supported natively in Verilog and VHDL
