Input values are used to access specific locations in memory, and the CPU stores these addresses in registers that are used for both instructions and data. With the help of the above statement, please list all of the registers used in the aforementioned processes.
ADDING AND SUBTRACTING The purpose of this assignment is to become familiar with the add and sub instructions. Addin' 'n Subtractin' 1. Assume the following values are stored at the indicated memory addresses and registers: Register %eax Address Value Value Ox500 ØX93FA1C9C Ox500 OXED Ox504 Ox7B %ebx Ox508 Ox79 %ecx Ox7 Ox50C OXF1 %edx OxA Fill in the following table, showing the effects of the indicated instructions, and showing what register (state the smallest unit that is affected) or memory location that would be changed and its new value. Also, show the OF and CF values AFTER the instruction executes. Assume each instruction is independent of the others. In other words, the initial conditions specified above hold for each of the instructions shown below. SHOW ALL VALUES IN HEXADECIMAL. What Changed? (list address or register) Instruction New Value (in hex) OF CF 1. subb $0xA, 12(%eax) 2. subb 8(%eax), %dl 3. addl %ebx, %ebx 4. addl %eсx, (%еаx) 5. addb %d1, 8(%eax) 6. subl %edx,…
Justify the following statements: i) The size of program counter is of 13 bits. ii) Direct address is of size 7 bits while indirect address is of 8 bits. iii) CALL and GOTO instructions, the size of program memory page is of 2K.
2. C code to Machine Code: Translate the following C code to Assembly code and then Machine Code. Assume that the variables, k, i and jare assigned to registers $50, $s1, $s2, respectively. Assume that the base address of A, B, C and D are in registers $s3, $s4, $55, $s6 respectively. Assume that the elements of the arrays A, B, C and D are integers: C[k] = A[i] / B[j]; D[k] = A[i] & B[j];
i. Briefly explain how the addition of 2 binary numbers takes place with the help of a flow chart using an Intel microprocessor.ii.Write a pseudocode for the above flow chart and a code in any of the simplest assembly language.iii. Perform i. and ii. above for subtraction operation.
Assume a CPU with a fixed 32-bit instruction length has the following instruction format:opcode mode [operand1] [operand2] [operand3]The mode encodes the number of operands and each operand’s mode. For instance, one mode indicates three registers, another indicates two registers and an immediate datum, another indicates a main memory reference, etc. Assume there are 94 instructions and 22 modes. Answer the following.a. One mode indicates three registers. How many registers can be referenced in this mode?b. One mode indicates two registers and an immediate datum in two’s complement. Assuming there are 32 registers, what is the largest immediate datum that can be referenced?c. One mode has a destination register and a source memory address (an unsignednumber). Assuming 16 registers, what is the largest memory reference available?d. One mode has two memory addresses, both using base displacement. In both, the basesare stored in index registers and the displacements are specified in the…
