硬件中断由外部设备触发,用于处理设备请求(如键盘输入);软件中断由程序指令引发,用于系统调用(如INT指令)。应用不同,硬件中断处理实时事件,软件中断实现内核服务。 1. **中断来源**:硬件中断由外部设备(如键盘、磁盘)通过物理信号触发;软件中断由程序执行特定指令(例如INT、SWI)主动发起。2. **触发机制**:硬件
What is hardware interrupt? What is software interrupt? What is exception? Please tell me all you know about interrupt.相关知识点: 试题来源: 解析 硬件中断是由外部设备触发的信号,用于请求处理器处理事件;软件中断是通过指令主动引发的中断,用于系统调用等;异常是处理器执行指令时遇到的意外错误或特殊情况(...
I would want to believe these interrupts stay with hardware for maximum speed and efficiency of the DMA. I would like to understand where within the TRM you are seeing indications of the sys_ndmareq[3..0] going to the interrupt controller for the ARM processor. Please cite the areas....

By contrast, hardware interrupts come from peripherals external to the CPU, whether the peripheral is implemented in the FPGA ot not. For example, if you have a slave peripheral, it could generate an interrupt by emitting an irq signal which is connected to Avalon along with the other slave ...
