Stack Subroutine Pdf Programming Computer Program The document discusses stacks, subroutines, and the 8085 microprocessor. it provides the following key points: 1. the stack is an area of memory used for temporary storage of information in lifo (last in first out) order, growing backwards into memory with the stack pointer register defining the bottom. 2. · a subroutine is a group of instructions that will be used repeatedly in different locations of the program. rather than repeat the same instructions several times, they can be grouped into a subroutine that is called from the different locations.
Stack And Subroutines Pdf Subroutine Computer Hardware The document discusses the stack, subroutines, and related instructions in an 8085 microprocessor. it describes the stack as a lifo memory structure that grows backwards. The stack is a section of memory utilizing as a last in first out (lifo). this operation is useful for keeping track of the program flow, i.e. the last subroutine call is stored on the top of the stack. If the link register already holds the return address of subroutine 1, it will be overwritten by subroutine 2’s address. since the last subroutine called is the first to return (last in, first out), a stack is the most efficient way to store these return addresses. How does a stack work in assembly language? ns to control the movement of data into stack and from a stack. these two instructions are push and pop. push – this is the instruction we use to write information on the stack. pop – there are two methods to add data to the stack: direct method and indirect method.
