- Based on the diagram below, what is the result for register AL after executing the mnemonic opcode/operand instructions? MOV AX, 0x0083 MOV BL 0x2 DIV BL AX BL AL АН 0083 02 01 Dividend Divisor Quotient Remainder The resulted AL is 43. The resulted AL is 41. Ob. The resulted AL is 30. O c. The resulted AL is 40. Od.arrow_forwardProgramming Project: For Loops Write an Assembly Language Program that produces the Times Table for a specific integer value between 1 to 12. NOTE: You choose and hard code only one value (i.e. 7) and produce the times table for that value. Also note that since you are using registers and memory locations make sure that at each step you screen shot each result for each part of the Times Table. For example 7 x 12 = 84 but in Hexadecimal the value is 54. Sample code in C #include void main() ( int i, j; printf("Enter an integer: "); scanf("%d", &i); printf("Times %d Table\n", i). for(j = 0; j<= 12; j =j+1) { printf("%d x %d = %d\n", j, 1. j'i); } printf("\n");arrow_forwardGiven the number Ox21100006, what is it when interpreted as a MIPS instruction? 1. The instruction format is type |. (R, I, or J?) 2. The opcode value is (specify as a hexadecimal value, e.g., OxfEE3, lower-case x, upper case hex values.)arrow_forward
- Why does the Str_trim procedure from Section 9.3 use the JNE instruction?arrow_forwardMANUALLY decode the following ARM machine language code to ARM assembly instruction. Ox56D54386 Write your answer in TWO parts, the Op-Code in a box and ALL operands in another box. The Op-Code of the instruction is: The operands of the instruction are:arrow_forwardAfter the ROL instruction is executed in the code sequence below, the final value for AL determines the values for the FLAGS. What is the value for the FLAGS? MOV AL, 1001_1100b ROL AL, 3 a. CF= 0, ZF= 0, SF= 1, AF= 1, OF= 0, PF= 1. b. CF= 1, ZF= 0, SF= 0, AF= 0, OF= 0, PF= 1. O C. CF= 1, ZF= 1, SF= 0, AF= 0, OF= 0, PF= 1. O d. CF= 0, ZF= 0, SF= 0, AF= 0, OF= 1, PF= 0.arrow_forward
- What is the main difference between the MUL instruction's multiplication product and the IMUL instruction, which only needs a single operand?arrow_forward(True/False): The PUSH instruction cannot have an immediate operand.arrow_forwardAfter the ROR instruction is executed in the code sequence below, what is the final value for AL? MOV AL, 1000 1111b ROR AL, 2 a. The answer is 1110_0111. Ob. The answer is 1100_0011. Oc. The answer is 1110_0011. Od. The answer is 1110_1011.arrow_forward
