- What takes happen if a stack resource generation fails?If SS = 3500H and the SP is FFFEH,(a) Calculate the physical address of the current top of the stack,(b) Calculate the lower range.(c) Calculate the upper range of the stack segment.(d) Show the logical address of the stack.(e) What is the range of physical addresses if CS = FF59 ?Suppose, you have 3 best friends named A, B, and C. CS = 1024H, IP = 1025H. SS = 1092H, SP = 1017H. Now, find out the physical address of the first instruction to be executed and the first location of the Stack to be used to execute the code.
- Assume the stack grows toward smaller addresses,i.e. calling pushl $10brings the stack pointer from0x80C to 0x808 Assume we wish to 'delete' 20 integers on the top of the stack.Write a line of assembly that deletes them from the stack by changing the value of %rsp Use decimal numbers in your answerWithin the context of the programme, it is important to distinguish between the Code Segment, the Data Segment, and the Stack Segment. The next task is to determine, for each segment, the combination of registers that was used to address the data items that were contained in that segment. This will be done by figuring out which registers were utilised to address which data objects.1. If DS = 7FA2H and the offset is 438E,(a) Calculate the physical address(b) Calculate the lower range(c) Calculate the upper range of the data segment(d) Show the logical address2. If SS = 3500H and the SP is FFFEH,(a) Calculate the physical address of the current top of the stack,(b) Calculate the lower range.(c) Calculate the upper range of the stack segment.(d) Show the logical address of the stack.(e) What is the range of physical addresses if CS = FF59 ?3. If the current value of the stack segment register and stack pointer are C00016 and F F0016, respectively, what is the address of the current top of the stack ?4. For the base and offset addresses in previous problem, how many words of data are currently heldin the stack ?5. Show how the value EE1116 from register AX would be pushed onto the top of the stack as it existsin previous problem.6. Assume that the DS register is 578CH. To access a given byte of data at physical memory location67F66H. Does the data segment cover the…
- Electrical Engineering Department Name: Microprocessors (8022125-4) - Chapter 2 Quiz 2 ins In some applications, all registers are saved at the beginning of a sibroutine. Assume thatSP=1932Hbefore a near subroutine CALL. Show the contents of the stack poiller and the memory contents of the stack after the commands: \[ \mathrm{AX}=15 \mathrm{ABH}, \mathrm{BX}=3 \mathrm{C} 16 \mathrm{H}, \mathrm{CX}=5678 \mathrm{H}, \mathrm{DX}=7823 \mathrm{H}, \mathrm{FP}=\mathrm{A} 43 \mathrm{FH} \]Write a subroutine finds the length of a string stored at address starting from address $1100 and stores the length in CPU register B. Program needed for HCS12 in Code Warrior. Assembly code needed. As soon as possible.So, what should happen when a processor sends a request that fails to be fulfilled in the cache while a block is being sent back to main memory from the write buffer, exactly?
