AXI Interrupt Controller

概述

产品描述

LogiCORE™ IP AXI Interrupt Controller (AXI INTC) 内核将外设的多个中断输入集中至系统处理器的单个中断输出。 用于检查、启用和确认中断的寄存器通过一个从接口访问,适用于 AMBA® 协议的 AXI(高级微控制器总线架构高级 eXtensible 接口)规范。可根据目标系统调整中断数量及其它方面。这个 AXI INTC 内核针对 AXI4-Lite 协议接口精心设计。


主要功能与优势

  • AXI 接口基于 AXI4-Lite 规格
  • 可配置中断输入的数量(多达 32 个)
  • 单个中断输出
  • 在 MicroBlaze 中,支持可重新定位的基址
  • 易于级联,提供额外的中断输入
  • 中断请求之间的优先级由矢量位置决定。最低有效位(LSB,本例中第 0 位)具有最高优先级
  • 用于选择性地启用单个中断输入的中断启用寄存器
  • 用于启用中断请求输出的主启用寄存器
  • 支持快速中断模式
  • 支持嵌入中断
  • 可配置软件中断功能
