Summary:A method and a device for performing stack operations within a processing system. A first and second stack pointers point to a top of a stack and to a memory location following the top of the stack. A first stack pointer is used during pop operations and a second stack pointer is used during push operations. When a stack pointer is selected, it replaces the other stack pointer. The selected memory pointer is provided to a memory module in which a stack is implemented, and is also updated. When a pop operation is executed the updated stack pointer points to a memory location preceding a memory location pointed by the selected stack pointer and when a push operation is executed the updated stack pointer points to a memory address following that address.
