第6题:
阅读以下说明和x86汇编语言代码,根据要求回答问题1至问题3。
【说明】
在某嵌入式安全监测系统中,对某任务的加工操作需通过数据采集(Collect_task)、计算(Calculate_task)这两个不同的程序段来完成,并且执行程序段Collect_task和Calculate _task的顺序及次数有如下约定:
Collect_task(2次)→Calculate_task(1次)→Collect_task(5次)→Calculate_task(4次)→Collect_task(2次)→Calculate_task(2次)
表6-22 所示为x86系统部分指令及寄存器说明。
采用逻辑尺控制法实现以上要求的汇编程序如下:
【汇编程序代码】
N EQU (1)
RULE EQU (2)
CODE SEGMENT
ASSUME CS:CODE
START: MOV AX,RULE
MOV CL,N
LOP: SAL AX,1
JC (3)
Collect: CALL Collect_task ;执行Collect_task程序段
JMP (4)
Calculate:CALL Calculate_task ;执行Calculate_task程序段
NEXT: (5)
JNZ (6)
MOV AH,4CH ;功能号送入AH寄存器
INT (7) ;结束程序运行,中断返回
(8)
END START
请根据试题的要求,将汇编程序代码中(1)~(8)空缺处的内容填写完整。
