PC/ATX中断控制系统使用性能的探究

The Research of PC/ATX Interrupt Control System Usable Performance

通过使用不同的中断请求线进行中断或中断嵌套服务的操作实验 ,结果表明 :IRQ2仍可作为独立有效的中断请求线使用 ;空闲的 IRQ1 0、IRQ1 2和 IRQ1 5都是外部中断源可选用的有效中断请求线 .本实验结果为合理、有效地应用

The interrupt services or nesting services are operated by using some different interrupt request lines.The tested results showed that IRQ2 is still independent and efficient interrupt request line; the freed IRQ10, IRQ12 and IRQ15 are selective and reliable interrupt request lines for external interrupt resources. The tested results provide reliable experiment data for PC/ATX system's interrupt control resources reasonable and efficient utilization.
