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**:硬件中断...
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(如除零)。中断是处理器暂停...
Other Parts Discussed in Thread:DM3730 When implementing any of the DMA request lines (sys_ndmareq[3..0]) on the DM3730, does this interrupt go directly to the DMA controller to process the next frame of data (entirely within hardware) or does it interrupt software? Then software in...
不清楚
It doesn't seem clear to me how to specify wether an interupt should be hardware or software. In the Quartus Handbook it does specify "SOPC Builder generates the interrupt controller in one of two configurations, software priority or hardware priority, depending on the interrupt signals pres...
Analysis of Software- and Hardware-interrupt handling (with and without cache)Adomat, JoakimLindh, LennartJ. Adomat and L. Lindh. Analysis of software- and hardware-interrupt handling (with and without cache). In Proceedings of the 3rd Design, Automation and Test Event, March 2000....
The correct choice is to use a Hardware Timer with Interrupt to call your function.These hardware timers, using interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using ...

Hardware interruptions will be modeled by external SDL signals that will be received by the passive processes. Theinterrupt prioritywill be indicated in the transition that will attend to that interruption. This transition will be the only one in the state in which the process is waiting for the...
