When the peripheral asserts this signal, we say that an interrupt occurs. 当外设发出这个信号,我们说一个中断发生。
In computing, an interrupt request by a peripheral unit, as opposed to a software interrupt written into a computer program. 在计算机系统中,由外部设备引起的一种中断请求,它与编写在计算机程序中的软件中断不同。
The CPLD implements the protocol of the peripheral bus interface, and sends data to Win32 applications through hardware interrupt and DMA in device drivers. CPLD负责处理PC机扩展总线接口协议,利用硬件中断和DMA,并通过设备驱动程序把数据传送到Win32应用程序。
