1.编写一个 32 位二进制数除以 16 位二进制数的除法程序.观察当除数为 0,或
超过相应寄存器范围时,程序执行的结果.
2.修改零号中断服务程序,使它具有以下功能:
(1)判断除数是否为 0,当除数为 0 时,显示相应的结果
(2)当除数不为 0 时,采用适当的方法完成商超过 16 位的二进制数的除法运算.
3.注意必须保护原有中断服务程序的入口地址,并在程序完毕前加以恢复.-1 to write a 32-bit binary number is divided by the number of 16-bit binary division process observed when the divisor is 0, or
Exceeds the corresponding register range, the result of program execution.
(2) modify the number zero interrupt service routine, it has the following features:
(1) determine whether the divisor is 0, when the divisor is 0, display the corresponding results
(2) When the divisor is not zero, using the appropriate method to complete more than 16 providers of division of binary numbers.
3 Note that you must protect the existing entry address of the interrupt service routine, and restore them before the program is completed.
