interrupt response

The interrupt cycle of the general I/ O card is at ns level, and the system realizes the control of the galvanometric scanner through interrupt response.

中断I/O卡的中断周期在ns级，通过系统实时响应中断请求来实现对振镜式激光扫描系统的实时控制。

For some of the interrupts such as the APIC timer interrupt and NIC interrupt, interrupt handling procedures are directly set in the interrupt descriptor table, in order to provide deterministic interrupt response time.

把一些中断例如APIC和网卡中断的中断处理程序直接注册在中断描述符表中，这样可以得到确定的中断响应时间。

Fir-st, we analyze how KVM influences the timer interrupt response times of the guest RTOS by studying the mechanisms of both interrupt virtualization and time virtualization of KVM.

首先，文章通过研究KVM的中断虚拟化和时钟虚拟化机制，分析KVM将对客户操作系统的时钟中断响应时间产生怎样的影响。

Realize the interface between PCI9054 and the PCI bus, including the bus arbitration, read and write of the registers, the configuration of the EEPROM, the DMA transfer, interrupt response and so on.

实现PCI9054与计算机PCI总线的接口，包括总线仲裁，寄存器读写操作，EEPROM的配置和下载，DMA传输，中断响应等功能。

But the traditional software time will arise the accumulative error because the time cycle is not considered perfectly, because of the interrupt response time is not confirmed, the error arose by the timer interrupt method is not rooted.

但是传统的软件定时方式由于时钟周期考虑不全容易引起累积误差，而采用定时器中断方式定时由于中断响应周期不确定性而产生的误差更具有非固定性的特点。
