What is stack pointer in 8086?
In 8086, the main stack register is called stack pointer - SP. The stack segment register (SS) is usually used to store information about the memory segment that stores the call stack of currently executed program. SP points to current stack top.What is a stack pointer?
What is stack pointer? A stack pointer is a small register that stores the memory address of the last data element added to the stack or, in some cases, the first available address in the stack.What is the size of stack pointer in 8086?
The stack pointer is a 16-bit register that contains the offset address of the memory location in the stack segment.- Instruction Pointer (IP): is a 16-bit register. IP in 8086 acts as a Program Counter. It points to the address of the next instruction to be executed. Its content is automatically incremented when the execution of a program proceeds further.13 oct. 2020
