Can you use stack in microprocessor for storage of data?

Yes, but not for long term storage, only while a program is executing using its stack.


What is the basic difference between instruction RET and IRET in 8086 microprocessor?

RET pops the PC off of the stack, while IRET pops both the flags and the PC off of the stack.


What is stack in 8085 microprocessor?

STACK operation in 8085 microprocessor.The stack is a reserved area of the memory in RAM where temporary information may be stored. An 8-bit stack pointer is used to hold the address of the most recent stack entry. This location which has the most recent entry is called as the top of the stack.When the information is written on the stack, the operation is called PUSH. When the information is read from the stack, the operation is called POP. The stack works on the principle of Last in First Out or Fist in Lat Out

How many machine cycles are required for RET instruction in 8085 microprocessor is?

RET instruction needs 3 machine cycles. One to fetch and decode the instruction(4 T states), and two more machine cycles(i.e. 2*3=6 T states) to read two bytes from the stack(stack is exterior to microprocessor, stack is in R/W memory, so to exchange data with stack needs machine cycles). Thus, RET instruction needs total 3 machine cycles and 10 T-states.


How much space did the Intel 8080 microprocessor have?

The stack size of Intel's 8085 microprocessor is theoretically 64 kb, but the real limit is a function of memory and program architecture and layout. The stack pointer is 16 bits, but that is not the same as stack size.
