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.How do you calculate stack pointer?
The stack pointer (SP) points to the top element of the stack. The current value of SP is (016E)hex. The CALL instruction is of two words, the first word is the op-code and second word is the starting address of the subroutine (one word = 2 Bytes).Is stack pointer a RAM or ROM?
Stack is always in RAM. There is a stack pointer that is kept in a register in CPU that points to the top of stack, i.e., the address of the location at the top of stack.- There are two types of stacks they are register stack and the memory stack.
