Interrupt Controller IP
Design IP
Overview

SmartDV’s Interrupt Controller IP is a high-performance solution designed to efficiently manage interrupt requests across complex SoC architectures. It enables seamless coordination between multiple peripherals and processors, ensuring timely and prioritized interrupt handling for real-time and embedded applications.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. It supports features such as nested interrupts, programmable priority levels, vectored and non-vectored modes, and integrates easily with industry-standard processor interfaces.

INTC
Benefits
  • Efficient Interrupt Management – Prioritization, masking, and optional nesting for responsive, deterministic handling
  • Flexible Trigger Configuration – Programmable edge-triggered (rising/falling) and level-sensitive (high/low) sources
  • Scalable Architecture – Parameterizable number of interrupt inputs and targets to fit any SoC size
  • Fast Interrupt Handling – Optional fast/urgent interrupt line with selectable source for minimal latency service
  • Prioritized Processing – Multiple hardware priority levels (parameterizable) for predictable resolution
  • Versatile Source Control – Supports hardware-generated and software-generated interrupt requests
  • Comprehensive Masking – Per-source masking and status/clear registers for fine-grained control
  • Seamless SoC Integration – Standard bus interfaces (AXI/APB/AHB) and straightforward register map for easy bring-up
Compliance and Compatibility
  • Compliant with standard interrupt-controller conventions (configurable to align with common SoC/CPU ecosystems)
  • Compatible with all major EDA synthesis, simulation, and linting flows
