Overview

The LogiCORE™ IP AXI Interrupt Controller (AXI INTC) core concentrates multiple interrupt inputs from peripheral devices to a single interrupt output to the system processor. The registers used for checking, enabling, and acknowledging interrupts are accessed through a slave interface for the AMBA® protocol’s AXI (Advanced Micro controller Bus Architecture Advanced eXtensible Interface) specification. The number of interrupts and other aspects can be tailored to the target system. This AXI INTC core is designed to interface with the AXI4-Lite protocol.

Key features

  • AXI interface is based on the AXI4-Lite specification
  • Configurable number of (up to 32) interrupt inputs
  • Single interrupt output
  • Supports relocatable base address in MicroBlaze
  • Easily cascaded to provide additional interrupt inputs
  • Priority between interrupt requests is determined by vector position. The least significant bit (LSB, in this case bit 0) has the highest priority
  • Interrupt Enable Register for selectively enabling individual interrupt inputs
  • Master Enable Register for enabling interrupt request output
  • Supports Fast Interrupt mode
  • Support for nested interrupts
  • Configurable Software Interrupt capability

Easy migration from Arm to RISC-V: an L110 case study

Last June, we launched the Codasip L110 RISC-V core, introducing the best-in-class solution for power-efficient applications. The L110 is highly competitive in terms of power efficiency and code density. Additionally, it is the first RISC-V core to support easy and risk-free customization while minimizing the verification effort required to bring these customizations to silicon.

A formal-based approach for efficient RISC-V processor verification

In this article, we go through a formal-based, easy-to-deploy RISC-V processor verification application. We show how, together with a RISC-V ISA golden model and RISC-V compliance automatically generated checks, we can efficiently target bugs that would be out of reach for simulation.

SOC Stability in a Small Package

There are some IPs in SOC which are of general use and malfunction on them impacts a entire SOC. We Identified these IPs and analyze impact on SOC due to their malfunction.
