This lecture covers the process of adding interrupts to a CPU, including the introduction of interrupt signals, special registers, and new instructions. It also discusses the implementation of a software dispatcher for interrupt handling, with fixed priorities and interrupt routines. The lecture details the generation of IPENDING, the control flow to the OS/user, and the identification of interrupt sources. Additionally, it explains the initialization of handlers vectors, stack management, calling corresponding routines, and returning from interrupt handlers.
