Abstract
In general, in one aspect, the invention features a method for reducing the elapsed period between the time an interrupt acknowledge is issued by a CPU and the time when the corresponding interrupt vector is received at the CPU. When a device connected to a lower speed bus sends an interrupt request, an interrupt queue device, connected to the CPU by a higher speed bus, intercepts the interrupt request, temporarily stores the corresponding interrupt vector and then responds to an interrupt acknowledge from the CPU by delivering the temporarily stored interrupt vector on the higher speed bus. In addition, the interrupt queue can deliver the temporarily stored interrupt vector to the CPU on a separate serial line.
