Based on operations illustrated in Section 2, write a program to evaluate the arithmetic expression X = (A +B × C) ÷ (D – E) Make effective use of the registers to minimize the number of MOVE or LD instructions where possible. All operands are initially in memory. The operand order for divide, DIV, is quotient, dividend, divisor. The operand order for subtraction, SUB, is difference, minuend, subtrahend. (a) Assume a register-to-register architecture with three-address instructions. (b) Assume a memory-to-memory architecture with two-address instructions. (c) Assume a single-accumulator computer with one-address instructions. * Operations can only happen between registers. You have to load operands from memory to registers, and the result from register to memory at the end, using MOVE or LD, ST instructions. " Operations can only happen between memory addresses, you don't have any registers. Try to use minimum amount of instructions, registers, memory accesses and temporary memory locations as possible.

Give a code that in Avr assemblyWrite and assemble a program to execute the following HLL statement. int r = 0; int n = 10; for (int i=0; i<600; i++) { r = r + n; n = n +1; } Use R20 to store the result of (r). Note that the final answer is not the correct answer as R20 is an 8-bit register (0-255) while the expected result is greater than 255.
In C, both long x and int *y are 8-byte values. How can we can tell which one is which in the assembly compiled from the C? (I.e., what is true of one but not the other? If several answers seem correct, pick the most precise option.) A. x is stored in a register, y in memory B. x is modified using addq, y using addl C. x may be an argument to add but y won't be D. When an argument of mov, a register storing x will never be inside parentheses E. When an argument of mov, a register storing y will always be inside parentheses
