The new module class, UartIntrSC is derived from the existing UartDecoupSC module class, whose header, UartDecoupSC.h, is included.

A custom constructor is declared, and a signal output port, sc_out<bool> intr through which the interrupt will be driven.

The new thread, intrThread is declared. It will use re-implemented versions of the genIntr and clrIntr functions from the base class, UartSC.

A Boolean FIFO is used to hold the queue of requests from the existing processes, rxMethod and busThread.

  sc_core::sc_fifo<bool>  intrQueue;
	  

The definition of the UART module class with interrupts, UartIntrSC may be found in sys-models/intr-soc/UartIntrSC.h in the distribution.
