The Stack

The Stack is an area of memory devoted to the current program.



$sp is a special register used to contain the address of the beginning of the stack being used by this procedure.

The Stack grows from higher addresses to lower addresses.

decrement by 4 (size of word) and use sw for each push

use lw and increment by 4 (size of word) for each pop

The Stack also contains local variables.

Activation record is a block of the Stack used by a specific instance (activation) of a procedure.

Why isn't it a "procedure record"?
