A. For each operand and result within each of the following
assembly language instructions categorize each addressing mode
using the 5-types framework of Figure 7.6. Each instruction
will have three answers to be listed.
LOAD R4,
12+R9 ; list modes here in order,
separated by commas (3 answers)
ADD R6, R5,
R4 ; list modes for ADD here (3
answers)

5.3 Rewrite the following program fragment that is written using the GPR instruction set for execution on a CISC processor that provides the same instruction set as the GPR processor but allows the register addressing mode to be used on the input operands or destination of any instruction. (Yes, the code fragment will execute correctly as written on such a processor. Your goal should be to reduce the number of instructions as much as possible. ) Assume that the program...

Q 2. Assuming a 32-bit operating environment, identify the mode of each operand in the following instructions. (Note: There are two operands in each instruction; identify both modes.) For a memory operand, specify whether it is direct memory mode or register indirect memory mode. Assume that the instructions are in a program also containing the code. .DATA value DWORD ? char BYTE *1. mov value, 100 2. movecx, value 3. mov ah, Oah *4. moveax, (esi] 5. mov [ebx], ecx...
