Abstract: A microprocessor is for detecting an interrupt request during execution of a program, saving contextual data elements of the program being executed, sending an interrupt acknowledge signal, and jumping to an interrupt subroutine if the interrupt request is still present after saving the contextual data. Otherwise, the microprocessor resumes execution of the interrupted program.

Abstract translation: 微处理器用于在程序执行期间检测中断请求，如果中断请求在保存上下文数据之后仍然存在，则保存正在执行的程序的上下文数据元素，发送中断确认信号和跳转到中断子程序。 否则，微处理器恢复中断程序的执行。
