Assuming that register EBX has an address of 0x20000000 and
register ESI has the value of “8,” what does the following
instruction do? Describe what happens to each register and/or
memory location (provide the address(es) and value(s)). Also, how
many bits are moved by this move instruction?

True false questions 1.If array is an array of words, and esi contains the address of array: mov ax, [esi+4] will move the third element of array into ax 2.After these 2 instructions run: mov al, 11b or al, 1 al still has the same value: 11b 3.To divide a value by a power of 2, the SHR instruction should be used for unsigned integers, and the SAR instruction should be used with signed integers. 4.The following statement will assemble...
Question 3: ARM Processor a) What is the number of bits in a general-purpose register (e.g., R1) of the ARM Cortex-M4 processor (CPU)? b) What is the number of bits in a memory address for the ARM processor architecture? c) What is the number of bits in an assembly instruction for the ARM Thumb-2 instruction set? d) Consider the memory map used with the TM4C123 microcontroller shown below. If the stack is in data memory, what is the initial address...
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...

may I get an explanation for the 3 parts in this question
Given that . Ar is a label at address 510 EAX has the value 139 . EBX has the value 102 Which bytes in memory will be accessed by the instruction movl $Ar + 38, %ecx Write your answer in the form startByteEndByte with no space in between. If memory is NOT accessed write -1 for your answer. For example, if your answer was bytes 527...

Questions 6-10: Prior to execution of the instruction MOV CX,[1234H) - following are the information given on the state of the processor CS = 0100H; DS=0200H; IP = 0000H; CX = 8B3AH Machine code for the above instruction=8B0E3412H; Answer the following questions 6-10 given below related to this instruction - 6. What is the content of the destination-operand prior to the instructions execution? a. 1234H b. 43211 c. 8B3AH d. 3A8BH e. Unknown 7. What is the content of the...
For questions 3-4, provide the full MARIE RTN (register transfer notation) for these new MARIE operations. Your answer should include the fetch, decode, operand fetch (if necessary), execution and store result (if necessary) stages. When you see X in these instructions, this is a main memory address (the last 12 bits of the 16-bit instruction) – refer to this as IR[11..0) and not X in your RTN. 3) AutoIncrLoad X - the autoincrement addressing mode is used to access a...
b. A microprocessor has an instruction set that consists of 117 instructions, which need fetch, decode, read operand, execute, write and interrupt stages. Assume that as an average, each stage requires three micro- operations to complete. Also, assume that the control memory is N bits wide (i.e., control field bits + address selection field bits + address-one bits + address-two bits N bits). The control field bits are 15 and there are 15 flags to be monitored. i. How many...
