1. Register addressing Write a program register.asm that adds register AH to register AL, only use the values that are currently in these registers. 2. Immediate Addressing Write a program immediate.asm that adds the number 5 to a constant called first1. Note that this arithmetic must take place in a register. 3. Direct Addressing Write a program direct.asm that subtracts var2 from var1, then places the result in answer. Declare all three variables in the data segment as words. Inititalize var1 as 3231H and var2 as 2217H. 4. Register Indirect Addressing Declare an array that contains the numbers: 1,2,3,4 (byte size). Use BX to point to the first array element initially. Subtract the second array element from the first, and store the result in the fourth element. Use the INC and DEC commands to change the array element that is pointed to. 5. Indexed Relative Addressing Repeat the previous problem, but use SI to point to the first array element. Use indexed addressing with a displacement value to access other array elements. E.g. do not change the contents of the SI register. 6. Based Relative Addressing Copy the top 2 words from the stack into registers AX and CX respectively. Do this without changing the stack pointer do not use POP instructions! Use BP as the base register. How will your program know what value to place in BP? To ensure that the stack contains some known values, place the following code at the beginning of your program: mov dx, 1234H push dx mov dx, 0ABCDH push dx
