Arrays and the Stack - Lecture – January 30, 2004
In all common processors that support stacks (including the 6502, 8088, and ARM) there is an extra register called the stack pointer, which decreases in value as items are pushed and increases in value as items are popped Stacks tend to grow downwards, and shrink upwards The 8088 does this as well |
