The x86 includes the following instruction: IMUL op1, op2, immediate This instruction multiplies op2, which may be either register or memory, by the im- mediate operand value, and places the result in op1, which must be a register. There is no other three-operand instruction of this sort in the instruction set. What is the pos- sible use of such an instruction? (Hint: Consider indexing.)

*ASSEMBLY LANGUAGE* A subtraction instruction takes two operands, subtracts the first from the second, and the result goes into the second. Write a 16-bit subtraction instruction, where... The first operand is stored at the memory address contained within the %edx register. (NOTE: To be clear, the %edx register contains the memory address OF the operand, not the operand itself! Recall the syntax of "indirect addressing," to use here.) The second operand -- also where the result shall be stored -- is stored directly in the 16-bit %bp register.

Please write down the microinstructions to implement the instruction MOV R0, [R1], moving the contents of the memory cell pointed by R1 tothe register R0. Please add a short but significant explanation to each single microinstruction. olve this question in great detail explaining every single bit of info as i'm a complete beginner and i need to understand how to solve questions of this type. also provide small examples of how the solution would differ if the question was slightly altered. THANK YOU!
