TOPICS : STACK & INTRODUCTION TO PROCEDURES
The Stack
The stack segment of a program is used for temporary storage of data and addresses. The item are added and removed from one end of the structure, and the processed in a “last-in, first-out”.
Represent an example of a procedure that performs binary multiplication by bit shifting and adding.
The Stack
Stack instruction are PUSH,POP,PUSHF and POPF There is no effect of stack instructions on flag.
The stackThe preceding stack declaration, SP.
The stack pointer is initialized to 0100h.
It is empty stack.
When it is not empty, it contains the offset address of the top of the stack.
Stack Instruction
PUSH source.Source is 16 bit
register.PUSH AL.Sp decreased by 2.
