Parallel Port & Nios II Interrupts

This lecture covers the design of a programmable parallel port interface for an Avalon bus, including the methodology, VHDL realization, and testing. It also explains the features and specifications of the typical SOPC system with Nios II CPU, focusing on parallel input/output interfaces. The lecture delves into the architecture of the Nios II processor, its core features, programming model, and interrupt services. It details the registers, control logic, and memory architecture of the Nios II core, emphasizing the trade-offs in system implementation. Additionally, it discusses the programming model registers, interrupt handling, and the relationship between ienable, ipending, and PIE for interrupt generation.
